This is what i have 85 El Camino 7.5 26 Spline 241 Gears

I have a sers 3 Locker (Cam Lock) i want to install

I orderd the spacer from Summit Motive Gear Ring Gear Spacers (http://www.summitracing.com/search/Brand/Motive-Gear/Product-Line/Motive-Gear-Ring-Gear-Spacers/?autoview=SKU)Summit Racing Part NumberMGR-075050
I was told this would work I cant see where it will work as there is a offset between the stck 7.5 Carrier and the Cam Lock GM the spacer has not got here yet will be today any help would be Great thanks !!!!:dontknow:

This is what i found out Just encase anyone else does this
The spacer willnot work on a sers 3 Carrier with the stock gears 241 Its a Thick gear so spacer wont work
the sers 3 takes a Thinner gear Summit has a richmong gear 323 for the sers 3 Carrier that will work and will keep me Prety much the same as far as my speed there part # is RGM 4900441
:nanawrench: what a Pain in the butt

Yea, the thick gear, or the spacer, is used to install a 3.23 up ratio gear on a series 2 carrier.

If I remember correctly, the 2.56 ratio is where the so-called dividing line is, requiring a different carrier for higher ratios.

If I remember correctly, the 2.56 ratio is where the so-called dividing line is, requiring a different carrier for higher ratios.
In a stock form the 7.5" series 2 goes up to 3.08 ratio.

I listed what i found out and what will work In the future if some one is doing what iam doing He Or she can find the Info
