I am finishing up my rebuild, going well. What options do I have for the rear axle to get both rear wheels moving. I have a 302, beefed up with a C4. Right now it is rear passenger wheel drive. Is there some kind of posi traction out there? Before I put the motor back I want to repace the master cylinder and redo all the brake lines, hoses and bleeders. What size line does it have? What bleeders should I use to replace. I think I will find the bleeders to be rusted in after 35 years. If they are rusted in is there any harm with penetrating oil and mapp gas to heat them up if I am replacing the bleeders. What line hardware will I need so I can avoid 10 trips to the auto parts store? Maybe I should try to take all the lines out in one piece and study them before I go to the store.
YOu need to heat the cylinder housing and not the bleeder screw. Metal expands when its heated. As long as the guts are removed, it should not be a problem.
like mavaholic said, you'll want the sorrounding metal to be hotter then the bleader. heating the bleader while its screwed into cooler metal will only make it tighter. since your pulling all that stuff off anyway you ever think of going with a factory 5 lug front disc brake system?
Also go to the Currie web site for rear end stuff. They carry a number of different type of lockers, etc. Also if you're lucky you can find an original ford rear with their version of posi. Getting pretty rare though. Sometimes you can find one on ebay.
most likely the lines are 5/16" you can find a trac loc posi on ebay all day long 28 spline or 31 spline for 9", but if you still have the 8", yeah, call currie or auburn. Eatons detroit locker is available for the 8" as well, it's around 550 though. But, the detroit locker will actually lock in place from the get go, and both wheels will spin, no slip. Posi will slip sometimes, if you do a lot of driving on back roads, might want to stick with the posi. Oh, perogie has them as well....
A good all round street strip posi thats not too" clunky" or jerky for the 8" or "9 is a repoduction of the Ford Trac-Loc called a Duragrip,sold by Randys Ring and Pinion,ringpinion.com,it has hardend hats and spiders with moly center pin and heavy duty clutches,it's way more stronger than a stock Trac-Loc and even those are pretty tuff.They have a standard one that is real smooth and one they call "aggresive"that will have a little chatter or jerk going around a bend but it almost unoticeable,I use them in most of my customer street rears except like a tubbed car with 500 hp,or more,or something with a trans brake.They hold up real well.
