Front Brake Lines Clip Screw Size and Type

[74Z28GC3]

I misplaced my original 74 Z28 front brake line clip screw to the subframe bracket that hold to two lines that come from the proportioning valve in a rubber bushing. Does anyone know the screw size and type? i have the other two screws and clips that hold the front brake line to the subframe.

So are you talking about the one that clamps the rubber bushing around the 2 lines? Mine appears to be 5/16 coarse thread 1" long.

Yes, that is the screw. I located my original screw and meant to post that I had founded it in my garage. Thanks Sean77LT for your reply.

^^^^ minor correction there...COURSE is an understatement! These GM FRAME screws are a PITA as they are NOT common bolts
A 5/16 COURSE screw will get you a 5/16-18....in the average world!
These are a 5/16-12

5/16"- 12 x 7/8 Screw
