That is a really good point on Miata swaps. Guys all over the country have problems with smog laws especially on 96 and newer cars with ODB II.
The 2 things that trip most guys up is wiring and exhaust and I probably made the wiring harder than it needs to be. I was trying to keep the Camaro BCM for the anti theft stuff in it but it turned out there are just so many other things it does it was impossible.
Watching the last couple road kill episodes I've been scouting for a 240 or 260 myself...
I really want something older than 79 because there are a couple car clubs around here with great events for cars older than that.
