Re: Smaller/thinner rear brake drum? Deep rear steelies won't fit!

This is a drum from my G20. It doesn't look as thick on the face as yours. Has the 2 3/4 brakes.

Boy...I agree. I think your drums don't have that taller outer lip like mine.

We'll know more once the part arrives. Fingers crossed!

Spartan locker is basically what's called lunchbox locker..it replaces the spider gears in a standard diff..
10 and 12 bolt rear have C clips that hold the axles in...you'll have to disassemble the spartan to get the axles out

Yep - I swapped the rear drums as @Nick_R_23 suggested....and they just - fit. Tucked right in.

The fronts took a 1/4" spacer, which I didn't anticipate....but they kept kissing the tie rod ends. The spacer took care of that, as far as I can tell. I give up 1/4" of wheel stud length - is that anything I should be concerned about? It's not ideal, I realize...but there is still a good 3/4" - 1" of thread sticking through the wheel. Think that's sufficient? With the tapered acorn-style lug nuts? Thanks @ShortHaul for his thread that chased down the same issues! The spacer worked for my fronts as well - so much appreciated.

I have yet to take it for a drive, so I may be celebrating a bit prematurely, but so far they all look like they're going to work! Wahoo!

I may need to put her on the road for a day or two to see what shakes out, but so far I'm feeling very positive. And it looks absolutely killer! More pics to come...

Thank you so much for everyone's help! I love this place!

So I finally got the wheels and tires sorted out....and took her for a shakedown run this morning and found her pouring fuel from the dual-tank valve. Awesome. Haha. Three steps forward, two steps back.

It's the single-wire, 6-port valve. Guessing those are almost impossible to find these days?

This is going to take a new thread, most likely! Haha. Darn trucks!
