700R4 Question
As I prepare for the swap. I was wondering if the C-4 alum. driveshaft would work in the conversion. The weight savings would be about 10 lbs. (guess) It measures 27 1/2" eye to eye, so it would need to cut down. I'm wondering if the yoke on the diff. side will match up? Did they switch u-joints in 84 or are they the same? These go for $10 to $20 bucks on ebay.

That's a great question Bud. E-mail me if you find out. I still need to get my driveshaft shortened, and would be interested in going to aluminum in the process ;) .

Re: 700R4 Question (Stingy74)
I guess I could go to the parts store and measure the u-joints. I'm not sure why the end shaft of the Dana 44 would be different that my 12 bolt.
Looks like they come in 27 1/2" for the 4+3 and 33" for the 700R4.

Steve-It's going great. Currently rebuilding the front end. New bushings, springs, shocks, etc. It was dancing all over the road, so I thought it was due. :eek:

Re: 700R4 Question (Budman78)
My new 700r4 shaft measured 64cm (25.22").
Original was 71.3cm (28.09")
In other words, it was shorted 7.3cm (2.88")
these are taken between the center of the yokes, should be ca 1" more if you measure on the outside as Stingy74
I think the driveshaft must have become shorter with the new 1980 diff.
See the 7004r page for more info on the 700r4 swap. (in tech section at my page)

Re: 700R4 Question (Ingar, Norway)
Update, I called O'rellys tonight and both the 85 and 78 share the same u-joint. So, if you want to save some additional weight a lite weight 85-91 alum. driveshaft for the 700R4 can be used. I will get a price on shortening next.
