67 Dart, 7" for 8 3/4 Rear swap- Driveshaft alterations-

Thanks for the feedback guys. 72bluNblu- good to hear back from you :-)
Yea- I thought it might have been my drive shaft was not all the way in and so I pulled it out, cleaned it a bit more, put it back in and is still too long so I'll get under to measure but 1/75-2.25" sounds about right.
Say- here's a thought- what year "A" Body would have had a shorter shaft stock? Like- the guy I bought the rear from said it came out of a 68 year car- I'm thinking maybe try to locate the driveshaft from that car as well if it's still in his barn.
