I am helping a friend build 1967 Mustang Fastback. Originally it was an inline 6 and a 3 speed transmission. We found that the head was bad on the 6cyl and was able to score a 302 that had already been rebuilt by another friend for a reasonable price. Far less than the cost to rebuild the 6 cyl. The transmission is a toploader with the id code of RAN S 1. Based on the information I have found, that transmission was used in multiple cars and trucks with small block V-8's and 6cyl. We would like to make this car a 4 speed and I know the id plate I am looking for is a RUG or HEH. Looking at the case we have I see that the RAN S 1 Plate is riveted onto the case and the case has the 8 bolt pattern where it mounts to the bell housing. I assume that the case is the same whether it is a 4spd or a 3spd and Ford just riveted what ever code the transmission was meant to be on the case.
Can anyone confirm my assumption? If my assumption is correct, what does it take to convert the case we have to a 4spd and do you have any resources on how to go about doing it?
Thanks in advance!!!
Never mind http://www.mustangtek.com/transmission/Ford3speed.html Found a good website with photos and codes for toploader's and they are completely different cases. I guess that's why we do research!
