It would depend what calipers are used , 70 pin style the hose threads right into the caliper , 72 slider type use a different hose , Rock Auto should list both by year . All years were front mount as I recall .
From my experience the mini starter will fit through the header if they are TTI headers , not sure if they are Dougs though
you could just plug the heater hose ports but the fittings are not hard to find & hose is cheap 1/2 pipe by 3" should work , even a hardware store pipe nipple could be used .
With the Serp system are going to run A/C on the car again in the future , if so you need a compressor minimum to route the single belt , it would be simpler to just use V belts short term I think .
Use Only a Melling oil pump high pressure std volume , Jegs should have them ,
Carb will mount with 5/16 bolts studs are preferred into alum though .
Any of the car magazines might be able to pull some parts in return for the story maybe ! Any one else we can think of that might sponsor some parts ?
