Nice progress so far. I'd recommend installing the horizontal shocks on the car when using the new control arms. Lots of people learned the hard way that wheel hop is intensified when aftermarket control arms are installed.
Still slowly moving along. I scraped the 86 Mustang, it was too far gone. The 91 Hatch will be going to the body shop after the holidays, the 92 Coupe is getting sidelined for a Coyote swap, and I bought a 86 TC from COLD. I'm slowly gathering parts for this project which I've named SR86.
Here's my take. Anything sensor related or reading resistance I solder. Everything else gets crimped with heat shrink over the crimp to seal it. And I use a Snap On crimper with a tang that pierces the plastic on the connector.
