T5 swap & driveshaft length?

[jocko]

It depends on what your T5 was born in. If an S10, yes, that generally requires a spacer. In the case of a Camaro trans (ideally with an S10 tailshaft for forward stick placement in a bench seat arrangement), a spacer is generally not required.

I needed a spacer but none existed when I did this, so "kinda" designed one and had a machine shop make it - it was rudimentary. Before I was done, folks were reproducing them, so I wish I'd waited, but it worked great. My trans was from an S10 and I was lucky in that it was also a WC with manual speedo connection - a desirable and kinda rare combo, not one I was smart enough to seek back then, but fortunately stumbled into it. If I recall, I either picked it up at the Pomona Swap Meet or the LA Roadster show one year, a long time ago, in a galaxy far, far away.. Then I learned the stuff in the link above, usually the hard way, along the way of figuring out what I had and how to stuff it in the truck.
