I have just rebuilt a 1971 351C motor... its sweet. I just assembled a C-5 Trans with a shift kit and torque converter. Motor went in smoothly and the tranny bolted up without just a couple minor problems. I now have the major problem of the tranny being .5" away from the crossmember mount..... Any solutions to this problem?? Any ideas would be great, and this is all going in a 73' mustang that already came with a 351C and FMX tranny. THANKS !
