Saginaw 4 Speed

[WTexChevy]

I just swapped a 3 speed for the Saginaw 4 Speed transmission. It was pretty straight fwd but I thought I'd share a few things I encountered.

Trans bolts right up. I did change clutch out but splines, pilot, etc. are the same. Bottom two bolt holes in m trans. were not threaded so I had to use two longer bolts and nuts.

Floor hole: I found a Hurst Comp. Plus 4 speed shifter and the floorboard hole is way off from the Daytona 3 speed shifter I had. Plan on some cutting/patching depending on what you got. Long "S" type shifter barely clears the bench and shifter sits WAY back on trans.

Slip yoke is different. Trans length is the same but the spine count on the 4 speed is 27. I believe it's the same at a TH350 yoke.

One question I had for anyone who has done this swap, did you fab a crossmember or let the trans hang like the 3 speed? I'm thinking about giving it a little support with something.
