Heidts Pro G drop spindles

[BigChevyFTW]

i was wanting to use the BMR suspension level 2 kit with the heidts spindle if it will work together.
i was going to use an ATS AFX Tall spindle but people have had very long wait times with them and the L&H kustoms spindle and i refuse to wait that long and be told 2 weeks, every other 2 weeks for 6 months like others have been told.

im going to try to contact Heidts tommorow and see exactly why they say you have to use thier control arms with their Tall spindle.

i was just trying to see if any of you guys knew why the Heidts spindle had to be used with thier control arms. they wouldnt tell me so i asked here.

thanks for the replies

Car is a 71 Chevelle SS 496 681HP@6400/689TQ@4500 - 4L80E 3000 stall- 12 bolt 3.73 gears
will see how she runs when suspension is done i havent even got to drive her around the block, i refuse to drive it until the suspension is done. i lost my last project due to not doing the suspension and crashing it 10 days after the motor was installed. very sad day for me i will never forget it.
