Hey Trevor,

I'm pretty sure that all '81-'85 FBs have the shifter in the same location (12A or 13B).

Since you are gong from an '84 to '82 .. you shouldn't have to worry about cutting the trans tunnel.

UnregisteredSA22C did his swap into an older '79-'80 SA .. so just a little more work since his shifter is in a different location.

The fuel tank from the S2 and S3 do not interchange. You will have to fabricate a slosh cup. You will also need a larger diameter fuel feed line. I used a roll of aluminum line that I bought from Summitt Racing. I bent it into position and flared it and then used the original feed line as my return line. Works perfectly.

As for the shifter, its in the same location so there will be no fabrication required.
