i built my own... the whole thing from scratch and i couldn't be happier.
i'm into the whole thing about $300 (includes everything) and did the whole thing with a torch and an arc welder.
box from 69 buick special - $25.00 (wrecking yard)
new pump to match ps box - $70.00 (auto zone)
pully for pump - $10.00 (wrecking yard)
borgeson u-joint (mounts to box) - $60.00 (borgeson)
pto joint - $8.00 (napa #338)
2 slip yokes for #338 - $24.00 together (napa)
these two yokes plus the joint make the complete
joint assembly which mounts near the firewall.
i used the pitman arm from the buick box, and lengthened and dropped it my self using 1 1/8 inch cold rolled steel as the splice (anything less will bend or break... trust me it took me three trys)
instead of a pillow bearing on the firewall i used 1/4 inch steel and made my own square mounting plate (3" x 3" i think)
3.5 feet of 3/4 inch hot rolled cost me $6.00 from
a steel yard.
I made my own pump and box brackets by taking measurements and trying different things.
spend some time and fool with it, and anyone can fabricate this on their own. it's not the prettyiest thing out there, but it works like a dream.
i'm 23 with little to no metal working experience (i have talented friends) and me and a buddy did this in two saturdays.
goo luck
