Paco, I have built 3 rods with Must2 power racks and 2 with Fatmans front for Must2 (you dont say which but assuming Must2)and have never used that late model of a rack. Always use the 74-78 Must2 power rack units with the Chev P/S pump on a 350cu. I get the RB's pump pressure reducer,if too fast, (40.00)valve goes in Chev. pump. The earlier racks have almost 4 turns the later that you are using are 3, thats why they are so fast and squirrly. the early non-strut front ends (A arms) need the slower rack. Also have used the 1" narrowed A arms and had to cut 1" off both ends and rethread tie rod, but you dont run into the unequal side to side you have or metric. Also, you need to make sure the swivel point where the tierod comes out of the rack, when the wheels are straight, is at the same swivel point as the lower A arms inner pivot for up and down travel. So you dont get bump steer. Hope this helps.
