The GM shifter "boxes" are the same width (3 1/2") as the Ford, but are shorter (4 - 4 1/4") fore-aft. Would the GM dimensions work if positioned at the hole in the floor?

If it were in the exact correct location it might work. It would need to come through the existing shifter hole in the floor or the box would hit. The Camero tail housing has the box at the end of the tail housing. I'm going out and taking some more measurements tomorrow.

Tony, there will need to be a bit of floor opening clearance around the shifter to allow for engine movement on the mounts; 1/4" is probably minimum.
Could you see your way to doing a little floor trimming if necessary?

Yea I might. I was hoping not to make any holes. I don't plan on ever selling the car and by time it goes it won't matter to me anyway. the original shifter opening is pretty small. something like this might work for the shifter. It is low profile: https://www.thegearbox.org/catalog/item/3819132/10399030.htm

I'm guessing your car doesn't have the access panel the early floor shift 4 speed cars have, forward of your shifter position correct?

No it does not.

Tony, as you work your way thru the possible shifter layouts, give a thought to the vertical space required over the forward u-joint. The aft end of the shifter in the link above has its lowest point about 2.5-3" below the top of the mounting block (the block with the stud sticking up) at the back of the assembly. The top of that mounting block would coincide with the underside of the tunnel.

Beauty of that type of shifter is thay really once you have the forward section you can fabricate the rest to fit your needs. Higher lower longer shorter. Long as it doesn't interfere witj the trans you're good.

That's what I had in mind. A low profile shifter connected to a remote shift handle. From measurements I took when the trans was in the car (but shifter box hitting the floor with about 1.5" to go) I think there is room for an arrangement like the photo. Might be a bit until I can get back to the car to mock it up again with the S10 tailhousing.

Making slow but steady progress. I got a S10 rear section. It looks promising. I need to get out to my storage unit and install it. The S10 also has a more favorable trans mount location and it is not angled like the Mustang one. The Mustang mount was so far forward the trans would interfere with the cross member.

It fits. Not much room on top of the shifter box. I will have to get creative with the shifter. I may have to extend the shift rail out the back of the box. I'm working on a solution for the driveshaft now.

Like this, Tony?

Tony H · #58 08-07-2020, 05:05 PM

That's pretty much what I had in mind. The longer Mustang shift rail can be cut and reused for the S10 shifter box with a stub out to connect to a U-joint or whatever I need to extend it to the shifter. It's straightforward enough at this point I don't need to spend any more time on my back in a storage unit. Thanks for the idea Frank.

A 3.5 coupe with a 6 speed Getrag just sold on BAT. It was a conversion from an Auto. Can't really see much from the photos.

I can't recall exactly how the shifter rod works in there without looking but doesn't the ball on the bottom of the shifter turn the rod left when you push right and pull it rearward when you push forward? Meaning your shift pattern would be mirrored if you use a linkage/universal joint type shifter attached to it? Definitely not the end of the world but it popped in my head. Still like the idea.
