HP Manifolds

been there done it, 30 years ago, they work and so do ford front hub and drum to adapt to large bolt pattern, forgot which year mustang. lol did alot and found alot that worked during my 383 fastback swap, over 30 years ago. I wonder if that junkyard still exists in
Athol, Idaho. sorry for going off topic, had to rant, as many things work. no use arguing about it.
