Hey all,
I'm completing my 5 lug swap. The fronts (North race cars kit) and rears (stock sn95 gt stuff from a friend) are in. I'm attempting to gut the proportioning valve and install the adjustable from Ford racing prop valve but I cannot get the fittings loose. I'm really trying to not destroy the lines. I've let it sit with penetrating oil but no luck yet. I don't have a torch. Any suggestions?

Which fittings? The firewall lines?

Pen fluid and flare wrenches are really your only hope.

Yes, the firewall fittings. I'll give it a shot. Thanks
