Re: Steel caps for 8.75" Mopars???
 

No one makes pro gears anymore for an 8 3/4. Well thats atleast what i ran into.

Re: Steel caps for 8.75" Mopars???
 

Yes, the 2070742 case is for the 1¾" stepped pinion. The only current source of pro gears (that I'm aware of) for the 8¾" uses this pinion...

So, it looks like the "smart money": is on the 742 case and a mini-spool???

I hate to break down this 2.73 setup in my 742, because it's dead quiet, but money being what it is these days (scarce!) and 742 cases being what THEY are these days (scarce!), I might as well do just that...but, it's going to be a 3.90...This engine combination doesn't LIKE rpms...
That's okay; it's a street car, basically....
Thanks again for all the good information, guys...

Gettin' too OLD for this *****...

Those third members are getting heavier every year; I ain't gettin' any younger, so I built a "labor-saving device" to aid me in my time of need (old age!!!)

Here are some pictures of my creation; built from a Harbor Freight tranny jack and some 3/16" steel plate, it will roll right up to the rear axle housing and adjust to the proper height and angle so you can just shove the third member right into place without having to lift the %#@*&$%#@!!! thing!!!

I also built a "cradle" to pick it up off the floor and hold it elevated so it's easily attached to the "labor saving device."

Now, I can change a third member without lifting anything heavier than a half-inch ratchet (used to elevate the jack.) Guess I could use an impact tool for that...

Anyway, here are the pictures, direct for my Photobucket account.

I THINK if you click on the "thumbnails" they will enlarge, somewwhat, for better viewing...

i like the cheapo tranny jack thing and i've got one, too.

btw, i bought a 742 empty case off ebay for 51 bucks + shipping....

Re: Steel caps for 8.75" Mopars???
 

That's a really good price ($51.00) I think!!!

I'll keep my eyes open.... thanks.
