I think I figured-out the CPP disk brake conversion kit. But need to get remaining lines to make it ALL right now. (I know if I go to remove front to back coupling it will do like it did at master cylinder and twist-off, even with a LOT of penetrating oil

)
I finished yesterday making garage doable to put truck inside to help making Wifey happy, (& pull-out as needed to work on what is too tight for space inside). It's a tight fit! With front truck bumper against shelves in back of garage STILL had to remove bottom hurricane wind reinforcement brace to clear rear bumper! Glad I have a workshop in back for more storage & things!
And while I am at it replace fuel lines (probably go with 3/8ths over 5/16ths?).
