I used braided stainless steel lines from somewhere but I think the rubber ones will just fine.
I had to trim the back plate to fit them but otherwise had no problem getting them on. I also changed my master cylinder to the 1" one from the 80 series. You loose the low fluid sensor but it is a good trade.
Hey, I grew up in Midland, I bet your snorkel is for fording Rio Wadley.
The stock ones will work fine, but if you want to bypass the junction and hard line, and use a soft line directly to the caliper, you can get some longer ones from NAPA ... Can't find, at the moment, but there's a faq or thread around here somewhere with part #s ...
I'm doing a 4R caliper install this weekend, too, with backing plate eliminator ... I got a set of SS lines to go directly to the caliper. Got them from Mark at marksoffroad.net
Thanks guys for the reply's. Somewhere I remember reading that the frame to axle lines from old toyota pickups would work but I have no idea where I read that. I would like to get rid of the hard lines because they are a pain to work on.
Vette60- thanks man
Dunbar- Yeah driving down the center with my mom in the truck was fun, she was freaking out.
