Swapping the Diff for LSD

[tichuang]

My FC ('90 vert) was an unlucky one that came with an open diff. Here we replace it with a LSD diff, from a '88 GXL:

Old and new, or old...

Nice! I'm going to pick up a blown diff for $30 next week and include it in my spare transmission rebuild project (since my diff is inside my tranny casing -- front wheel drive).

Someone once described it as "mechanical crack" =)
