Brake proportion value fitting sizes
Hi To all
Does anyone happen to know what the sizes are for the proporate value on a 67. Having several fords from 67-73 this appears to be all the same. I never can seem to find the right fittings when redoing the brake lines and do not want to spend the money for pre bent
It appears these are 3/8- 24 and 7/16-24
Can anyone confirm?

I can go out and check on mine in a little bit, but...
drum brake trucks <1976 didn't have a proportioning valve.
They do have an "H" block, AKA distribution block, in which the brake failure light switch resides.
Disk brake vehicles from the factory will have a proportioning valve to dial down the rear brakes.
Many people that convert the drum brake trucks over to disk brake have claimed that a proportioning valve is not needed on the conversion- no problems with the rear brakes locking up.
I'll report back in a bit with the size of fittings...

The H block I have sitting on the shelf uses the same fittings you mentioned - 3/8" & 7/16". 2 each.
And it looks like the brake warning switch is also 3/8"
Oreilly's used to have the 3/16" x 4' long brake line with two 3/8 fittings already included.
I can't remember if they had the 7/16" fittings though.
Napa surely would.
