Upgrading a 91 W/Rear PBR Brakes to Front 1LE.
My 91 Formula came with stock rear PBR brakes. Is the PROP valve any different between my car and a 1LE? I might be upgrading my front brakes to 1LE.
Did some searching couldn't exactly find it.

I just put the front 1LEs on a 89 car with a PBR disc rearend, didn't swap the prop valve and they work good.

OK good, I was thinking the valve would be the same since the 1LE use the same rear brakes.

Shouldn't be an issue. There's a combination valve for each of the three braking applications: disc/drum, disc/standard disc, and disc/1LE.

or just take the spring out of the stock prop valve and put an adjustable valve in the rear line to really dial in your brakes..
