BBR's 83GT - 552 BBF version 3.0 (at least)

congrads,
I'd get new bolts if this is your d/w car..

[Bob Holmes]

Fantastic, great job.

I will not be doing DW this year, but I am going to keep a very close eye on them!

Started the manual brake conversion today. I pulled the booster out (had to remove the valve cover to get it out!) And bolted the adapter plate in. That's as far as I was able to get today. Looks like I will need to make all new lines from the mc because I do not think these will come close to reaching.

Are you going to a smaller bore master cylinder?

[BBR]

These cars already have a 7/8" bore m/c, so I am just going to do the modification Stiney showed. I imagine it will be fine.

[squirrel]

Yup, it should be fine.

[BBR]

I decided to go ahead and replace the master cylinder since I was going to have to make new lines. The common swap is to put a manual brake master from a Ranger on it. This flips the lines to fender side keeping them well away from the headers. At $12.99 + core from OReilly I though it a wise investment.

Ranger MC is 7/8ths bore? CRAP, I was just about to pull the trigger on a pricey '94-'95 SVT Cobra MC . . .

[BBR]

Stock '83 GT m/c is 7/8".

Ranger is actually 15/16, but those that use it report no ill side effects from the additional surface area.

Speedy, look on RockAuto, they list the sizes. There are several available for the Mustang. example, 79 Mustang 4cylinder:

WAGNER Part # MC99084 {#F99084}
Power brakes; 7/8" Bore; w/Vacuum Boost

[38P]

Thanks! I almost wasted some coin. O'Reilly wanted like $90 for the Cobra MC . . . and had to order it (which is the only reason I paused). I'm ready to "swing iron" once I get the brakes done)

[Beagle]

I meant to say also, watch the threads. They put funky metric threads on some of them, so you may want to verify what is on the car currently.

[38P]

It's already going to have to have a boat-load of adapters to hook up the Hurst Line-Loc (included a free kit with a bunch of tubing and adaptors) Nothing has been easy or cheap so far, so I'm not expecting good things here either.

[Beagle]

no doubt.

Congrats on the 10 at altitude James.

Cool! Nice to see ole four eyes hauling some oats.
