Aluminum Drive Shaft Options?

The Crown Vic driveshaft I used had 1330 ujoints.
The "Conversion" to a 7260 Mopar actually spec out to be for a 91-93 Dakota. I used a Neapco Brute Force 20599BF
You are correct the crown does use 1330 not 1320 joints. However I already had both trans and rearend yokes for 1350s so that what I hunted for. One neat thing is that there is a adaptive joint which is 1330 to 1350 and I'm told it is a very strong unit.

fklskv, The van unit was brand new and had new 1350 joints on it. Exactly what I needed but I had to shorten it several inches. Thanks, Max
