70-71 & 71-72 front and rear challenger bumpers the same?

was wondering if anyone knows if I can put 70-71 bumpers wo/jack slots on a 72 challenger?? are the bumpers and or brackets the same fit? thanks, Tony

Yes they will bolt right up, same brackets. 73-74 is completely different.

Yes they fit no problem.

Lighter too.

thanks guys....really appreciate the quick response.....BEERS!!!

Another question....which aftermarket bumpers fit the best??? AMD?? Goodmark?? Others??

Thanks, Tony

As others have stated the 70-71 style bumpers will bolt up to a 1972 model

However, as an FYI - as usual the 1970 is a one year only part. For 100% factory correct parts the 1970 bumpers have details that are different from the 1971 bumpers.

Also all years 70-71-72 use a different corner bumper rubber piece even though there is only one reproduction offered as correct for all years

What are these 70 and 71 Challenger differences? A late 71 will have slotted 72 bumpers.

Also what are the part numbers on the "other" corner fillers?

.which aftermarket bumpers fit the best??? AMD?? Goodmark?? Others??

Thanks, Tony

Anybody put AMD?? Goodmark?? bumpers on their 70-72 Challengers??

Which are the best fit??

Thanks, Tony

There are four different front bumpers on a 1971 Challenger and three different rear bumpers on a 1971 Challenger over the production year.

Now even more confused....AMD & Goodmark probably only make one of those......

Very happy with AMD front bumper

The 71 bumpers have no jack slots. I slid the 73 front bumper brackets rearward and used 72 rear brackets on my 73. It has 71 bumpers. (also a 70 grille).

Yes 1971 Front and Rear Bumpers do have the slots in both the front and rear bumpers starting in June of 1971.

Front Bumper Time Frame Parts book number 13-64-3

August of 1970 to February of 1971 was one front bumper.
February of 1971 to June of 1971 was another time frame for a front bumper.
June and July of 1971 was another front bumper that had slots for the Jack.
You also have the rubber bumpers in 1971 on Challenger the only year.

Rear Bumper Time Frame Parts book number 13-66-3

August of 1970 to June of 1971 was one rear bumper.
June and July of 1971 rear bumper had slots for the Jack.
Also there was a Ruber Bumper on a Challenger in 1971 and 1971 only.

Cool stuff but what are the differences?

I have 5 1970 Challengers and 2 1971 Challengers. One of the 71s is a rubber bumper car.

Would like to know the exact differences in the non-slotted bumpers.

You seldom get enough 1971 Challengers in one spot unless at a bigger Mopar show. Someone in the business of stripping and selling parts might be able to tell you the differences between the front bumpers from 1970 to the first bumper put on a 1971 Challenger. Maybe they are the same but different part numbers. What is the difference between the first bumper in 1971 and the second bumper Feb to June. The last front bumper has the slots, is it the same as the second front bumper but has slots. I have an early built 1971 Challenger and a late built 1971 Challenger with the slots. Is the last slotted bumper on a 1971 Challenger the same as an early 1972 Challenger Bumper. Why change just the front bumper half way through the 1971 Year and not the back bumper. The last change in 1971 to the slotted bumper is to prepare for the 1972 model year. My Late built 1971 Challenger has lots of the 1972 changes on it.

OK - I'll check out all my cars and see if I can spot the differences

I am also going to look in the parts book to see if any other parts of the bumper system have a Break Point date in February of 1971. I only know of one other Challenger close to me that is built between February and June but it has had rubber bumpers added. Need to see a Challenger built in that time frame to compare with the Challengers I have.

I used AMD front and rear bumpers on my 72 Challenger.
They fit and look great.

All my sheetmetal is AMD.
I bought one Goodmark piece and it didn't fit very well so I have stuck with AMD all the way through my project.

Thanks for the input....

Here are details on the rubber bumper fillers. Will post photos of the different year bumpers later

Part #'s
1970 models: 2962344 and 2962345
1972 models: 3464064 and 3464065 (may also be used on late 1971 models)

The main differences between the bumper fillers - See photos for reference
> skirt length of rubber on side and bottom is longer on the 1972 part
> the 1970 fillers do NOT have any internal support - material is all rubber
> the 1972 filler is molded over an internal solid support
> the 1972 filler has a noticeable extra tab molded into the rubber (along the groove) this fits into a notch of the bumper
> the part numbers are molded onto opposite sides of the part

See attached photos

skirt length of rubber on side and bottom is longer on the 1972 part
also in bottom photo note extra rubber molded on side of 72 filler to make part more rigid

the 1972 filler is on left and 1970 filler on right

> the 1972 filler is molded over an internal solid support

> the 1972 filler has a noticeable extra tab molded into the rubber (along the groove) this fits into a notch of the bumper

1972 filler on left and 1970 filler on right

bottom photo close up of the 1972 filler showing tab that fits into notch on bumper

Here are the reproduction rubber bumper fillers

Not certain if there is ONLY one vendor manufacturing the parts but this style does not have the correct factory features as the 1970 filler. The repro fillers available more resemble the later filler style

Still trying to locate the rubber fillers I had from an early 1971 Challenger. However, may have tossed them with another 1/2 dozen or so fillers because they were bent or torn.

Finally had the opportunity to take some photos of the different Challenger bumpers.

The photos show the different shape of the corners were the rubber filler part is mounted
For the different rubber fillers parts - Refer to the photos in my earlier post.

These are all original bumpers. A photo of each year 70-71-72 follows


The 1970 model uses the one year only unique bumper
Note that the bumper corner is smooth - there are no cut-outs which corresponds to the 1970 only rubber filler style

1971 Challenger bumper from a Sept 1970 car

Note that the corner area is already changed from the earlier 1970 ONLY style
Not certain when this change over occurred but this early built 1971 car used a bunch of the 1970 parts in the interior

1972 Challenger bumper

This bumper also has the cut-outs in the corner though the location seems to be moved forward and more defined compared to the the 1971 bumper which fits the tab molded into the 1972 rubber filler

This difference maybe the result of the stamping process that was used for manufacturing the bumpers

I have this rear bumper removed from a 72 Challenger.
I don't have a 70 to compare to but do you know if 70-71 area shown here underneath the bumperette have the same characteristic, rounded down or is it straight across

Terry,

I have the rear bumpers for all 3 years, 70-71-72, so I can check that area and post photos of any differences

Terry,

Checked the bumpers and ALL of them [70-71-72] have the same contour as the one shown in your photo - rounded under the bumperette mounting area.

I did notice one difference on the 1970 bumper - the bolthole that is used to mount the bumperette is "round" and NOT "oval" shaped

Thanks for taking the time to check and provide this information
