Hopefully get this thing all lined up and back in the car. It has not been on the road since the early '80s! Looks like the RobbMC dowels ,I'd put loctite on the set screws for the final assembly.

When I did that, it totally screwed my number and I had to start over again. I tried the lakewoods and wound up drilling and slide hammering them out. I finally just ordered the Robbmc ones and within a short period of time after I got them it was within book spec.

Also that brings up a good point , the picture the OP put up shows his dial indicator is not inside the bore of the bellhousing ... at least it looks that way ??? but the picture is small ... if that is the case he isn't really getting an accurate reading... but probably close enough for a caveman ...

I put them in a drill press and used a straight flat piece of metal to hold some very fine sandpaper against it and sanded it down very lightly. Using a caliper to check to see that I didn't remove too much material. Got it down to the size of the factory dowels I took out and with the holes COMPLETELY CLEANED OUT, I greased them a little and slid them in. No problem turning them with a screwdriver. I didn't have time to wait for others to be shipped here so I worked with what I had. I'm sure there are better out there, but I didn't work too hard to make these do the job.

Do you really think the number will be "a few thou" different? I'll bet you the change doesn't show up on the dial indicator! As for John having it surfaced ... another instance of him needlessly spending someone else's money. Yes, by all means check the runout, but if it is out of whack its easily resolved with shims cut from feeler gauges or pop cans instead of dishing out $100 to have it surfaced.

I never suggested anyone spend their money needlessly, I just said how I would spend MY. I doubt it would cost $100 to surface the bellhousing, even in the part of the country with high per hr labor charges ... Last edited by JohnRR; 03/01/13 03:30 PM.

My question as I have never heard of machining the bell housing to be parallel with the block, which surface gets re-surfaced ? the block side or the transmission side. I think a person can micro a project to death trying to get something perfect when there is tolerance that is acceptable . it's ok to butt heads, just don't do it with a butthead

I've had a chance to think about this , it's completely possible that the block could be the cause of the bell being out of parallel and shimming , as much as a half ass way of doing it in my mind is probably the best way to go .

I could not get my set up adjusted so that the indicator was fully centered in the bore but it is inside the bore. The picture was taken looking slightly down and from the left. The part that contacts the bore is as close to dead center as I could get it.

Does the set up not look right? Your setup is fine. Maybe one in 50 people will have a dial indicator and stand that will actually fit inside that hole! So the indicator is at a slight angle ... big deal, as long as it stays that way throughout the entire travel around the hole it doesn't matter. And John, the proper surface to machine would be the trans mounting face, not the block face. The main reason being that less material would have to come off but also there would be a good chance of cracking an iron housing if it is taken off the block face.

A standard size indicator will not fit inside the hole straight up. The surfacing of the bell housing would be easier to do the transmission face only if the block face was flat. it's ok to butt heads, just don't do it with a butthead

I checked mine every 45* and could watch it go from - to + back to - or 0 depending on the position.

Tim It depends on Ma Mopar to make them that way I've seen them like that, it depends on where you start your readings at to what readings comes off of the indicator Mr.Cab Racing and winning with Mopars since 1964.

When he puts in the proper dowels and does it again it should only be off by .001 side to side and .001 up and down.

Yes, I zeroed the dial indicator at 12 o-clock and called that zero then took a reading at 3, 6, and 9 o-clock. The you tube video showed taking readings more frequently. http://www.youtube.com/watch?v=tS4H4oImDhE Last edited by moparmedic; 02/26/13 01:08 AM. 1968 Coronet 1968 Charger 1966 A100 Pickup 1967 Barracuda 1970 Challenger 1972 Challenger 1973 Barracuda 2021 Ram 2500

I do the 45 degree, use a marker on the bell housing face, take a 360 reading , do a adjustment , do it again and again and again. wish I had a friend to do the wrench cranking it's ok to butt heads, just don't do it with a butthead
