never have done that swap on a chebbie, I am fairly sure it will require either a special bellhousing or an adapter. Might want to check, I know Lakewood and McCleod both make a bellhousing with the correct bolt pattern to put a Tremec behind most any Ford motor.

On the pedals, maybe a set of hanging pedals mounted to the firewall??? Wilwood and other companies have them. You might also want to consider a hydraulic clutch, makes the installation a lot easier than clutch linkage.

Should make the chebbie pickemup a super cruiser!!!! Keep us updated on the progress.....
