Cobraii,
A look at these PIC's (Posted by Greggers [A nice & helpful Guy]) should give a clear understanding of why the "drive shaft" will not fit the V6 Conversion.
The length of the shaft is almost as long as the car.
The front yoke pictured has a large collar that must be removed.
The diameter of the shaft itself is way too large for a good fit even if cut down.
After going through the trials of finding a '88 - '90 T-bird drive shaft which are becoming extremely scarce, I contacted a good DriveLine shop for help.
They suggested I provide them with the length (distance between the tail shaft of the transmission (T5) and the flange of the Rear assy in the car (in this case it was a SV rear assy).
Paul A has provided
part numbers for the yoke to be used in the T5 application
and the Alpine .
I also have the mfg & part numbers of the yoke my DriveLine Shop provided me for the shaft assy I had made. (Not to find them).
Hope this helps you and any one that might have a few questions on: Who, What, Where, When, Why and How
I surely do enjoy this Forum and all of the Folks that contribute
And a special thanks to Greggers for uploading these PICs'....
