73+ Caliper install

Might work but why? Buy the right hoses and be done with it.
My why? It's all about the next owner of the vehicle. They need a hose for 73 disc brakes... order that and it works. They need a left side caliper...order that and it works ( they need only to figure out how to bleed it ). We are building Frankensteins of these 50+ year old vehicles. If you'll sell it to whoever, Tell them "good luck with it". If you'll leave it to a family member, there are ways to make tomorrow easier on them. I have made some wiring and other changes in my 67 A-body. Every change has been documented and stored in that car that now belongs to my grand daughter. I'm just different I guess. I'm not a purist but when I see a vehicle for sale and description states multiple aftermarket brand names ( Edelbrock, Fitek, MSD, on and on ) it aint for me. I couldn't leave her with a 1967 Plymouth that needed Chevrolet Camaro disc brake hoses. OK, I could document that too, so she knows what parts to order. Wherever I can un-complicate... I do.
