If you can weld, get a mustand shifter and modify it to the specs in my swap howto. If you cannot weld you'll have to get someone to weld it for you.
Clutch and BH are the same, yes.

Might want to drop Central coaster a PM though. A lot of my initial ZF vs 4+3 knowledge was from the FAQ and posts on here, which have turned out to be pretty bogus information. I've driven a few ZF cars and only had one apart for a clutch job back in 2003.

Hello,
Can anyone tell me the proper shifter position (length of transmission from front of bellhousing to center of shifter) for early C4's?
Does anyone have a 4+3 out of the car they can measure?
I am considering an alternative transmission for a swap.

Yes, it will be the same as a ZF, but I don't know what that dimension is.. I have searched and searched without any luck....
I am considering a R154 (supra turbo) transmission as they are readily available here. I have a friend who has used one behind a LT5 for 4 or 5 years without any issues.
If the shifter position is ok, I will investigate further. Bellhousing and clutch are readily available.

If the Supra trans works behind an LT5, its using a deeper BH and consequently a longer input shaft than the one for an SBC. I think the diff is about 1.25". Someone else could verify.
Good to hear from you again. How's the 383 running?

The supra-LT5 BH was a one off.. The supra-SBC BH's are available off the shelf here from at least 3 manufacturers that I know of. Its been done a thousand times in other cars with small chevy's.
I have barely driven my car in the last year.. Work, baby and life in general... you know
I'll be back into it soon though. I have a pile of parts to go in, and I have a lift also now, so that makes it all the more enjoyable to work on too!

ZF6 swap
I think I have one on the floor from a supra turbo we blew up a few years ago. I remember looking at it a few times. Anyhow, the transmission is needs to be 30-31" from bell housing to tail shaft. The shifter needs to be at the 30" mark, and about 3" over to the left from dead center.

OK I am new too this but I see this is mostley about ZF6 speeds. I have an odd problome. I have a 85 corvette with a custom built zz4 383 storker. The car was a 4+3 to start it has a 700R4 raptor setup in it now that was put in for drag racing and a valve body setup went bad and blew the clutch packs in it. The car still has the clutch pedal and slave for the 4+3..IN fact I have to put the clutch down to start it still. I picked up a ZR1 zf6 speed for a very good price but I have no bellhousing or clutch. I want to put this in the car. What do I need? was the drive shaft changed for the 700R4? Do I need a new one for the ZF or since it was a 4+3 does it line up? what other parts do I need?
The ZR-1 ZF has a longer input shaft. Won't fit right on an SBC.
