Some more questions before the donor goes to crap metal:

Do I need the donor Throttle cable or will I be using my 85 cable?

what about the transmission shifting cable or any part of it from the donor, do I need to keep to use?

do I need to keep any part of the exhaust after the Y?

This last one is just something that I just thought about looking at the donor engine bay, what about brake master and booster, are any of these two of any use/benefit and easily adaptable to the truck?

thanks.
