This is the transmission in my 1968 GT fastback, 302 V8. The selector shaft (pin?) shattered and we're having terrible trouble getting the replacement part here in Ireland. Basically we can't get them! These are the number from the passenger side of the transmission: RF-D9BR-7006-AB C-2604194 FORD It is a 4 speed manual, reverse upper left. I think it may be from an F-100 truck? Where on-line can i get new parts for this?
