Nice job
You lucked out with the wiring and especailly the headight switch, I have seen cars burn to the ground by a ailed hl switch (mostly the rheostat that shorted out)
Hey Sponge, while your at it why don't do the headlight relay mod?
You'd be safe once for all.
oh yeah, before assembling the whole IRS, check the arch on the shoes. The stainless PB shoes are known to be arched wrong. I had a set, they were junk. I used normal repalcements back then but retained the other stainless hardware. Worked fine.
