disc brake checklist

That car looks gorgeous in gray. You got some options with the proportion of valve, you can go with a factory replacement disk brake one (might have to bend your lines a little to make it work. Can't remember if I had to). Or get an aftermarket adjustable one and keep your drum proportioning valve. I put a wilwood adjustable valve where the main body line meets the rubber line going to the rear end.

For the alignment, others might get skeletor about it, but I didn't get one after my swap. Just see if it feels weird driving or if the tires are wearing bad after. If not, meh, id leave it.
