Looking 4 Cheap Posi !!!
I have a 1979 F-150 with a 3.00 geared 9 inch rear end that I'm building for my wife ! It has a 1987 5.0 (E7TE) roller motor that I've ported both sides (intake & exhaust) ,added headers and a "68 4bbl intake from a Mustang with a Holley of course ,the truck also has a bulldog 4spd , what I'm looking to do is toturn my rear end into a Posi unit without spending a bunch of $$ or doing a crap job like welding the spiders , I heard of an article years ago called $1.98 posi , something about adding shims to the spider gears , but not sure about it and can't find anything about it !Does anyone know what is the cheapist way to get a Posi without spending major $$ !? I'd like to keep the 3.00 gearing or going higher 2.75 or so, for fuel economy with the bulldog first taking off is no problem ,but I'd like to have the Posi !! Can anyone help ??? Thanks in advance !! ...cougar...
