Hi, I've been lurking on here for a few weeks as I need to get my truck lowered.
I've got a velvet green 68 Doublecab and still not worked out the best way yet. lol
I'm going to bookmark this thread as I've been thinking of the same beam, front and rear brake set up for my double cab.
Thanks for post as its probably saved me a good couple of hours of searching :D :D
