1972 Duster Twister / 318 / 727 / 7.25 axle
Greetings -
I'm finally getting around to getting my 8 3/4 swapped into my Duster (as an upgrade and to address weird drivetrain noise that I 'thought' was a pinion bearing) Today I crawled under and started removing the driveshaft and realized....no movement forward after pulling the u-joint straps. I got around to shining a light on the tail shaft and there is NO silver showing on the slip joint. It is jammed up in the trans and bottomed out - rear axle is at full droop at this point so we should be seeing something.
I know (well, my gut says - no fender tag) this car did not come with a 727 and likely born with a 904. Also, seems like I remember a 727 has a 3" longer tail shaft housing than the 904 as well. So, I am thinking that whoever monkeyed this transmission in the car never shortened the driveshaft and just caveman'd it all together. I was able to get the shaft out after basically destroying the u-joint.
So, I guess the question is - how much damage can I expect to the transmission with that driveshaft being bottomed out for so long. I don't know how long this trans has been installed like this. I've driven the car very little in the 9 months I have had it as I have been working on it.
Thanks in advance!
