master cylinder
 

is the back line closest to windshield for the front brakes on a 93

the front one on the abs valve assembly block is to the front brakes so you are correct the back one on the master cylinder is to the front brakes.

thanks, i think im going with manual brakes

the brakes on these are bad enough when power assisted, i would think standard brakes would be really bad.

the whole car is a gut, so its gonna be pretty light. im hoping a different bore size on the new master will help
