A couple pics of the stock seat I custumized to my liking with Trans Am rear buckets a refurbished consol from an old Pontiac and some extra foam.
I got the thing wraped it Black imatation leather with white Stitching. I dont have picks on the finished product, ill try i get them soon.
Attachment 671051
Stock seat strip and preped for revival!
i kept the original foam and whent from there
striped the rear seats from the trans am
Attachment 671052
From there I measured and cut evrything to fit, I had to fab up a braket for the console.
Glued my pieces together, used duct tape to hold everything in place While it dried.
Attachment 671053
Once everything was glued, I slaped on on other layer of foam for look and comfort!

Attachment 671094
Instaled a Locked (clutchpack) AuburnGear diff this summer along with all new bearings, cups and seals
I kept the spindels the where fine.
I kept the 3.40 gears that i had, and had never heard of before (usualy GM is 3.42), the ring gear had a litle wear from used bearings but it doesnt make a peep. All in all with the diff, bearings, cups, seals, oil and gasket i spent apbout 700$
Attachment 671095
Here with the alignment paste, we can see the wear i was talking about (note the absence of paste on the bottom left side of the tooths.)

But everything works great! ;)

Re: My GMC Sierra Grande: Project GOLDIE
 

Thanks, ill try and keep it up for future projects, and ill try to snap a couple of the ones iam missing, such as the finished seat and instaled engine.
I wanna get a picture of the 3.40 stamp on the ring gear too, since its not common. If you guys have requests... just ask!

Re: My GMC Sierra Grande: Project GOLDIE
 

did you count the teeth ? must be a 3:42

Re: My GMC Sierra Grande: Project GOLDIE
 

nope its really a 3:40 Ratio theres no doubt about it,, counted the teeth and everything. 10 on the pinion et 34 on the ring, ill snap a pic next time i open the diff... pictures are worth a thousand words they say! lol

Any one ever heard or seen this before, i researched a bit and found nothing

Re: My GMC Sierra Grande: Project GOLDIE
