Really good advice coming at you. I've just installed a Pertronix unit on my 230. Most of the aftermarket wiring set ups are very well identified as to where they go, and with some patience, you should be able to get it done without putting a fire to the shop with the truck inside(intentionally). The weakest part of most all these old trucks is the electronics, so anything you can do to ugrade them is money in the bank.
