Yea I got the housing somewhere else as cass hooked me up with all the goodies... the guy who welded on my moser ends also welded on the perches... no the guy is not anywhere remotely near me... got the housing shipped in.. I am going to go out again today and triple check measurements... Mopar Performance

Off of both the tranny and rear end in relationship to the 90 mark or what? If in relationship to 90 degrees are both measurements on the same side or opposite sides of the 90 mark? If both are on the same side then you need to subtract them from each other which would equal six degrees difference between the two angles, if there on opposite sides of the 90 degree mark you add them together which ends up equaling 12 degrees like you posted, which is way to much see pic above for the measurement on the dana i am gonna triple check it all again today... but im sure they are opposite Mopar Performance

I put in a lowering block (cut) to get ideal piniona angle... now off the tranny centerline -3 and the snubber pad it was +2 I was -1 down that way.... and +2 the other way thats a 3* swing which is alot to me Now note.... I am no bracket racer but after the 5th pass setting the pinion angle up the way mopar muscle said on the return lane at cruising speeds i developed a slight vibration and no vibes under acceleration.... I am thinking i gave myself way to much pinion angle and that could be why my 60fts sucked also with the vibration... 1.78 was best i could muster.... BTW when my 60fts went down my mph kept going up.... I am no bracket racer but tried... maybe someone can make sense of it all. Mopar Performance
