Kel,i thought i told you that?no Gremlins ever got the 727 only the Bw crapbox auto in 70-71 and the Mopar 904 and 998 auto .The hornets from 72-77 got the 727 with the 360 option i believe but then again hornets are longer than grems so you still neee to shorten the shaft so you need to shorten the shaft and i haven't been to my shop lately but next time i will measure the driveshaft for you but maybe someone on here might help you as well anybody??
