Is the brake line port closest to the firewall for the rear brakes or does it even matter? Is the fluid displacement the same from the master and then adjusted at the proportioning valve?

 

I know you've got a truck bed full of parts,
but have you considered the Chips Motor Sport master cylinder?

It's a direct fit large 1 inch master cylinder tailored to your needs. it just drops in, no rerouting of your brake lines is necessary.

 

The rear line goes to the rear brakes.
I do not see how that is a direct fit, considering the stock unit has a line on either side. That looks the same as the 929

Yep wrong picture. Chip's Motorsport will machine the lines on what ever side you want stock or 929. Here is Rob's picture for the rx7 to 929 swap:

 

Had I know that was an option it's the way I would have gone, however I do not have an extra $250 to spend, but I do have a 929 master cylinder

I appreciate it
