Did 78 Bronco's come with CV type rear driveshafts? I'm looking to use one on a SWB, where it'll connect to a NP205. I'm told the 78's used 1310 series u-joints and were held on by u-bolt straps, but don't know about the CV part, which is what I really need. Can anyone confirm?

Confirmed

Thanks dude!:beer: :beer:

:D

Do the '78s use 1310s? My '90 uses 1330s.

Confirmed again. On the 1310 and CV part..:p

Yes 1310,Yes CV, BUT NO on the straps. Rear of the rear uses u -bolts not straps, and the CV in the front is a normal CV hook up. BTW, Not all 78's used 1310 :rolleyes: If it came with the 400 and C-6 it had 1330. In 79 they were all 1330.

Hi,

What about the 1980 to 85 Broncos, were thier CVs 1330 as well?

Thanks
Russ

Yup, as far as I can tell, they all came with 1330 series from 79 and on. 78 was kinda like the left over year from the EB's.

My 78 has both of those - the 400 and C6, and it still had 1310 joints on my driveline. I wonder if the difference was with the Tcase. Mine came with a 203

Nope, difference is in the year. 78's came with 1310's, 79+ came with 1330

That's what I thought. Normally, I trust what Erik has to say, he's seemed to know quite a bit about the first Big Broncos, but I felt I had to say something

Don't mean to step on your toes, Erik... ;)

I wear boots most the time, and have thick skin,, no worries here.

Keeping in mind I'm quoting from a Spicer book here, and we all know Mother Ford has used what ever is on the shelf more than once regardless what is spec'ed for the MY vehicle....

in 1978 there were no less than 8 drive line set ups, in 1979 six different ones.

And yes I noticed there is no listing for a 400 motor in 79, and I am not positive why. It may be as simple as Spicer did not supply the DS for that model. That is usually the case when a listing for a model specific entry is missing.

Lastly, it is VERY common to have a non OEM shaft installed when you take a vehicle in to a drive line shop to be worked on (or your shop out sources the work) There are many possible combinations to get the vehicle back on the road, which is usually the most important desire to the customer, not maintaining the OEM setup.. And if the customer is happy, the shop is happy.
