Do you guys think that I would need a bigger master cyl. to feed the larger wheel cyls of the F350. Keep in mind a '92 F350 rear axle and maybe the fronts are the same as the F100. Not sure.

That Colour would then be known as "VERMILION" for our Orphan Years Trucks.
As "VERMILION" was one of the Colours offered by FoMoCo '57-'60.

Mine had a Dodge truck dual master in it when I bought it ages ago. Mid-70's vintage I think.

I have the same motor/trans setup. Can you show me a picture of your throttle linkage and return spring setup? Thanks

Nice placement for that booster. Usually those are on the frame under the cab. However, a lot of cars and light trucks had the booster located on the left inner fender, but they were smaller in diameter. That was before they started mounting them to the firewall.
