Brake line question.

[k5blazerguy]

Out wheelin at the lake and motor mount shifted which caused harmonic balancer to hit the brake line going into the proportioning valve.
Question is…..does anyone know off hand what size the fitting is? My plan is to put a 90 fitting on the valve to get little more clearance and reflare the brake line. It’s the main feed coming from the master that feeds the rear brakes.

wow that's really close. Idk for sure what size it is, no help. What mounts you running? and do you have the brace plates between engine and mount ?
I put DIY competition mounts and the plates back in and it raised the dampener away from the cross member nicely

Looks like you need new motor mounts.

The brake line for the rear is larger and I believe it's 1/4" as for thread size I think you'd have to measure it.

7/16 20 inverted flare for 1/4" and 3/8 24 inverted flare for 3/16"
