Another n00b.

Thanks! It's been a lot of work but it's finally paying off. I swear that car just wanted to go sit under a tree and rust, it finally came around to my way of thinking.

A straight axle TR4 would make a good swap candidate, the IRS version is OK but the rear camber and toe change would make it less stable at high speed. An RX2 or RX3 rear axle is narrow enough to fit under most LBC's and Miata/RX7 diff stuff plugs right in, my car has an RX2 housing and a 4:30 Miata r&p with a 2nd gen clutch type limited slip. I also used Miata front steering knuckles and brakes, had a machine shop redrill the rear axles for 4x100 bolt circle.
