I am pretty certain the transmission mount bolts (Both going into the tail housing and the mount itself) are 7/16" coarse thread bolts. Someone must have put a heli-coil in your old trans. As far as the driver side speedometer housing. Every Super T I have seen has the passenger side speedometer housing. Got any pictures?

 

Old:

New:

 

I have one of those ST-10's out of a later Camaro,and it has those odd sized bolts on the tailshaft housing..They are metric,but I don't know what size.Worst case just swap tailhousings.

 

Ok I will try a couple other metric sizes. Something along the lines of the 7/16 equivalent.

I would rather keep it all in one piece so I don't mess something up with the tailhousing swap. I have 0 tranny experience.

Are you referring to the old or new? I always thought later model camaros, 79+, were always the nodular iron case with the 3.42s.

 

I don't remember what year exactly,I decoded it once,all I remember it was a Norwood trans,I believe in the late 70's.It is an aluminum case,with 2:64 first gear.Here's a link to some good info.

I have used that site to decode these. Very good reference site.

Are you sure the iron one is a t10 and not a saganaw? I don't know much about manuals, I'm just spitballin here

Yes, I used the site stated above to devode it. The iron st10 was used behind a 305 flamingchicken.

The biggest problem really is the bolt thread and the shifter linkage clearance. I dont wanna have to bolt everything up just to realize I need to remount the shifter.

I am not a fan of that shifter. Every bend in the shift rods is a flexing point if shifting aggressively. It might cause gear jams which will mean you will need to get under the car and physically move the linkage. Are you using a factory 4 speed console?

 

Yes it was a factory 4 speed.

Well it's all I have to work with. I looked at the shifters again and looks like I will have to use the old shifter. No big deal though it worked perfectly fine.

Once I get these shifters dialed In even the 2/3 shift is flawless. I haven't had problems with them.

Edit: I dont know how a "thumb down" thing got there. It was accidental.

 

That iron ST-10 looks like it's one from a 1982 Camaro / Firebird, not a 2nd gen Camaro / Firebird. From the picture, it looks as if I can see the reinforcement for the torque arm. That would explain the speedo output on the drivers side. It would also explain the problem with your shifter.
