for the first gen to a second gen frame----you need the second gen motor mounts-----everything else works with small adjustments-----over fill the getrag by one quart----the factory fill hole allows the main bearings to go dry-----do not ever speed shift the getrag because the shift rails are delicate---when you slam the gears one will break then you will be in 2 gears locked up and not knowing what might have happened----the tranny mount will be a little off--the driveshaft will have to be made---the floorboard shifter hole will shift forward---may have to bend the shifter to keep it out of the dash......
