OK this question came up today. I have a 68 gtx 440 4 speed partial vin on motor trans and dash all match. The question came up about the 22 inch radiator. Was it normal for 440 4 speeds to come stock with a 22 inch radiator. And was 26 inch just an option if you wanted it??? Thanks Larry J

I believe it had to have at least a 3.55 gear to come with the larger radiator unless you had a/c or towing

I must of had 383's on the brain. These guys are right 440 4spd = Dana = 3.54 or 4.10 = 26"

3.23 sure grip no ac. The reason the question came up is it does not have the correct rad in it. Part # is for an automatic car. I do not have the correct part # if someone has it please share. 68 GTX 440 4 speed. Thanks Larry J

The '68 FSM lists rad# 2898047 as standard equipment for a GTX 4spd. The size is not shown, however the parts book lists that part# as a 26".

My experience with 69-69 B bodies is that 440-4spd have 26" rads, not 22".

Also, a 3.23 axle does not seem correct for a 4spd car. According to the dealer data book (and my own experience), a 440-4spd would have the 3.54 Dana as standard equipment. An auto trans 440 would have the 3.23 as standard equipment. An auto car would also have the 22" rad (like you have) as standard equipment. Perhaps something has been changed?

Well I know the vin#s are correct. I checked the block the trans and dash before I purchased the car. No build sheet but does have fender tag and the rear end is not original to the car BOM 69 but the fender tag does say 3.23??? The 4 speed tunnel appears factory, welds and finish look correct to me and the dash has the yellow reverse light and wiring appears oe and correct. You can usually tell if someone added the 4 speed. The tunnel welding is usually the tell and then the wiring is usually wrong. But they would have had to fake the trans pad and the fender tag?? Its possible but when I purchased the car I did not pay a premium price. If you went to all that trouble I would think it would be for $$$$$ ?? Anyone else have 4 speed gtx with a 22 inch radiator that you know is original??? This is the same conversation we had in the garage today??? Thanks Larry J

it doesn't sound right ..
i had a 68 x 440 4 spd it came with dana and 26 inch rad opening..

Which transmission is shown on the fender tag? I believe "3" is 4spd, "5" or "6" is automatic.

Does the 6 digit order# on the tag match the rad support and trunk lip stampings?

EDIT; might as well check your engine code also, "83" is 440HP. What is the code under "AX"?

I think you maybe correct. The person I bought the car from. Did not have a lot of knowledge of Mopars nor do I. He bought it the same way I did. I and he felt like if the partial vins matched on the motor, trans, and fender tag it was what it appeared to be?? But i am not building it to sell. I want to keep this one. But I also would like for it to be correct if that makes since. Looks like it would be $$$$ to put a 26 inch radiator in it. Would that be a complete core support?? And then the cost of the rad. Not sure its worth all that. Thanks Larry J

A correct car would be "worth" it, what info is on the fender tag?

Fender tag does say 4 speed and 3.23 sure grip yes the SO # match the body. But I did not even know what a SO# was until I purchased the car. Like i said novice to mopars. I just think if you were going to go to all that trouble to stamp a trans and redo the tag it would be for $$$ . Maybe someone before us did pay a chunk a money for the car but I didn't and the guy before me didn't. Well none the less I am putting it back together for me to keep. Maybe i will put the 26 inch in??? Honestly its still a 68 GTX 440 4 speed with a dana and I love to drive it. Well I did before it went to the paint shop!!Thanks Larry J

Sorry I did not mean to say VIN on fender tag. I meant to say dash. So the motor and trans match dash vin. Partial vin on motor and trans are the same as dash. SO # also matches fender tag. Car is in body shop so I have no pics right now. But I do know enough to say the motor partial vin# looks correct. I think it would be hard to restamp that one. And the trans appears to be correct as well. But as I am learning it is amazing what some people do with these cars. And not just Mopars. Big block Chevys Fords ect. I think of the 7 I have had over the years at least 3 of them I ?? But all had good documentation. I started buying GTO's because of the PHS documentation no ? about what you are buying. Well live and learn. Like I said its my 1st Mopar project and its still going to be an awesome car when we are done!!! Thanks LJ

What are the first 6 digits of the VIN?

RS23L8A

No ? about it being a GTX. The question was is it possible to have a 440 4 speed with a 22 inch radiator and 3.23 sure grip. We know the rear end is a dana but is not original to the car BOM 1969 dated. Thanks Larry J

It seems from all the info given that the 68 GTX engine & 4 spd & dash may have been swapped into a 68 RR car that originally had a 383 & 4 speed & 22" radiator.

Looking at some old post. This question has come up before so I guess I am not the 1st to come across this. Is the whole core support different? I do not have the car here so I cannot look at it. Can someone tell me what I would have to change to put the 26inch radiator in?? I still think the motor and trans match. But who really knows its 45 years old and like I said people do all kinds of stuff. Rebody fake tags cut #,s from one car weld them in another and the list goes on. It is too bad Mopar does not offer a service like Pontiac PHS. Then you feel a little better about what you are buying. Thanks again my Moparts brothers!!!!!!!!!! LJ My brain hurts!!!!!!!!!!

Did 68 RR have rocker molding and wheel opening moldings?? This car has factory holes in fenders rockers and quarters and gtx lower quarter emblem holes do not appear to be drilled. You can tell the rockers are fenders and quarters are all factory holes not someone drilling them in the back yard. I have seen cars that have SS emblems put on the to make a plain jane chenille into an SS big block car. No matter how well you think you drilled them they are always off. So I don't know??? Thanks LarryJ

I meant chevelle .

Can someone post a picture of a factory 4 speed tunnel weld and also mine does have that same seam sealer you find in the trunk seams but some has chunked off so I can see the weld. Also I talked with one of the guys at the body shop and he feels like its the correct factory tunnel not after market and weld and seam sealer. Maybe the ? is would it have seam sealer on the tunnel weld??? Without a BS we may never know!!! Thanks LJ
