Proportioning Valve

[50 F1]

Working on brakes on my 50 F1.
It has GM front disc brakes. 72 Monte Carlo
Ford drum brakes rear 9" rear. Narrowed rear. Large tires and wheels (wide)
Is there any reason I should put a adjustable proportioning valve on this set up or will a non-adjustable one work?
Thanks Mike

I would suggest an adjustable valve. The reason is I have years of experience driving cars with this combination, and in low traction situations, wet roads and so forth the rear end can overpower the front end causing the front brakes to lock and you loose the steering. I hit a tree with my Marlin about 15 years ago in that type of situation. A adjustable valve will allow you to dial the rear brakes back a bit.

I will be putting a adjustable one on.
