I just got back from the junkyard and saw a Previa S/C with Rear disks. I was wondering If anyone knew if the Previa uses the same 8" diff as the 2wd pickups? The axle itself Looked the same except for the mounting points of Previas 4 link system.

Could anyone shine some light on this for me?

If it is in fact an 8" diff, I am planning on getting a V6 third member and a supra LSD, and I will be in business

 

I have a 7.5 inch previa 3rd member and detroit true-trac in my truck. I didn't personally pull it so I don't exactly what model... It does look very similar if not identical to the rear end on my moms supercharged previa.

 

A quick search told me the S/C came with a 3.70.
The NA previa came with a 4.30

Im curious where the build tag is on em. Ive looked for em at the JY. But never spend enough time lookin.

If its a F code, why not try to swap backing plates on your drum axle with all the disc hardware. Toyotas are stupid easy interchangable.

Then get your MK2 supra F code LSD.

 

we counted 3.73 on mine

 

my truck's 22RE auto came with a 3.73 rear end on the 7.5"

 

I had 3.58s stock. I initially just wanted a core to rebuild with my LSD. I figured a little lower gear ratio couldn't hurt and the price was the same. I do kinda miss my old gas mileage and highway cruising speed though.

 

Yah the rear disc setup is usable. I saw a Taco in Minitruckin Mag with Previa rear discs setup.

 

Ok just to clarify... Just take all the disk set off the previa axle along with the backing plate/ hardware and it should fit up onto the P/U's 8" axle just fine minus the drum setup?

Im fairly good at fabricating, so some grinding and drilling holes won't be much of a problem... but any extra little info will help.

 

I haven't done it but I almost went through with it. The only other thing I know is that the Previa rear discs have a drum brake type setup for the e-brake. Meaning the center of the rotor(hat) still works like a drum brake (with a cable I believe). And then there is the regular caliper for actual braking.
