All: I am finally in the process of building my Street Beasts Cobra. I have already ran into a pretty good problem with the differential, being in a bind.
I found out the "ears" on the frame for the upper control arms were welded wrong by Street Beasts (surprise). I contacted SB support
and got them to measure another frame and that's where the problem began. My "ears" are 9/16" off, shifted towards the passenger side.
I have since cut one of the upper control arm brackets lose, but still have the binding problem, which seem to be "inherited" in a Mustang style set up. And we know Street Beasts didn't build the Mustang, thank goodness!
With the frame on jack stands, diff. jacked up, and the upper control arms installed, the differential "shifts" about a half inch or more, towards the driver side. With the upper control arms off, it drops straight as an arrow.
Here are my questions: Have any Street Beasts builders had this problem and how did you solve it?
Would there be any difference in the length of the upper control arm for a 9" over an 8.8?
I am considering replacing the "stock" upper & lower control arms with after market ones, but there is no guarantee that will solve the problem.
I know StreetSnake had a similar problem (or worse) and went with coil-over's on the rear, which I'm game for that too.
I have seen where Ford "compensated" for the binding problem by using "softer" bushings, which "over time" would "self adjust". I want it "right" from the get go.
Any and all suggestions will be greatly appreciated!
Sincerely,
