    I have been racing a Pinto in ITB.

    Hate to change to an 8" just to put a LSD in.

    Any ideas?

    LOL! I've raced Pintos since 1975 and haven't seen a 63/4 lsd since about 1980. Put a 8" in and forget it. Woun't slow you down one bit, and their bullet proof. Get one out of a v-8 Mustang 2 and it should have a 3:55 gear in it. Try it/you'l like it.

    Thanks for the info.....

    That's kinda what I thought.......

    My 6 3/4 is a "Lincoln Locker" and probably not the best for cornering.

    OK, I'll bite...what is a Lincoln Locker?

    My first 6 3/4 was locked (in despiration) with DevCon "iron", packed into the bowl of the carrier. Axles were put in place and the "stuff" was allowed to set. Used it for a driver's school at Summit, and races after it. Never found any iron in the diff oil after that.

    Eventually, I found out how to lock it with welded spiders that were placed into the diff during assembly.

    Welded diffs in a rear drive car (I can only speak about solid axles) require an adjustment in technique, but very driveable.

    I've only seen one LSD, which I sold to a Saab guy that eventually used the internals to fit into his own carrier. I believe the axle spline counts were the same.

    Good hunting.

    You've been working WAY too many hours lately, due to the storm damage, so I'll let you slide on this one but....

    "Lincoln Locker"

    Could easily be "Miller Locker" or "Hobart Locker"

    ...as in welded!

    I though the 8" only came in the wagons and some of the V6 models. I don't think it is legal in the 2.0 and 2.3 versions. It is also heavier which makes more unsprung weight and more weight overall.
