Hey all, I'm getting a disc brake rear end from a 81 model GSL and I have a few questions. Firstly, while the Mazspeed tut doesn't mention the proportioning valve, I've noticed that some people recommend getting it along with the axle. What exactly is the difference between the valve I have now and the vavle from the GSL? What difficulties would I have if were to leave the original valve in place? Secondly, has anyone had any success finding an adaptor to make the hard lines on my '79 work with the lines for the rear calipers? I was hoping I wasn't going to have to replace all the hard lines. Could I just get a new fitting and flare the existing lines? Thirdly, the mounting points for the links didn't change between '79 and '81 did it? I know that the 84/85 models had lowered the mounting points for the trailing links, but I want to make sure I won't run into any suprises from the '81 axle. Finally, is the rear sway bar on the '81 thicker/better than the rear bar on my '79?



Thanks in advance for your advice.

um basically all the links are the same from 79-85 so swapping any axle is no biggie. the lines are easy too you just have to go and make some with the sa end and the fb end, or there might be an adaptor for that too.

the 81 and later sway bar is smaller than the 79's, try both its easy to swap, and you might actually like it without the bar at all
