I did mine with parts from an 84 turbo regal, except the mc as I didn't like the look of that big iron mc.
Are you looking for bling, ultimate stopping power, just something to get by?
Lot of options. Kirban is a great vender so supporting a board supporter is nice. The other two I've only read about. I would call each of them and see what you come away with. Service after the sale is nice.
I got my pwr steering hoses and hb unit for the tr, and mc for a Cadillac from rockauto.com with the 5% code it was a bit over $200 shipped. Bought some trans cooler hose and a brass tee for the return local. Also a 16mm/18mm flare wrench for the fittings on .
Definitely looking for stopping power, and thanks for the info I greatly appreciate it
