Don't use a glass pack muffler. The soot will clog it in a few days and you'll have a straight pipe lol

If you don't need power brakes, you can delete the booster vac pump. You either open the lid and remove the vanes (they slide out) or remove the diaphragm, depending on which type you have. Its not typically the starter itself that wear out, but the little brass bush that resides at its nose, pressed into the transmission housing. They're a couple dollars. Best to pick up a spare now so you have it. You remove it with a thread tap and press the new one back in very gently with a threaded rod and a nut by tapping with a small hammer.
