Hi guys, anyone here got an aluminium drive shaft on their a-bod? What did you use, are there any cheap options? Chopped down ram shaft for example? Be keen to hear what's out there.
The problem with running an aluminum driveshaft in our cars is the diameter causes exhaust fitment issues.
Long,,~55" center to center.What was the original length on that?
Long,,~55" center to center.
That length just so happens to fit my 3.6L, T5, 7-1/4 perfectly.
Funny how some stuff works out like that huh?
That's cool. I may look into that, although mine will have to be shortened pretty substantially if I go that route when I install a T56 behind my 340. It's already longer than the driveshaft with a 340/A833/8.75".
My research disclosed that the Crown Vic shafts were excellent candidates if you could work with 1320 (Ford HD) joints which I believe is their common size. Because of that I got the Ford van unit which was long enough to shorten to my needed 55" and although it filled up the shaft tunnel I had no exhaust so it worked great at a fantastic cost.
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.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
