Biggest offset with AFX spindles

[67CamaroLSX]

Building a 67 Camaro. I have the new Rocket racing pro touring wheels. The front wheels are 18x8 with 5" offset. They won't work with 2" drop spindles because of the backspacing. I tried the ridetech truturn system but won't work because of the f body oil pan on the ls engine. The car came with QA1'S and couldn't get the front low enough with stock spindles. Looking at the Speedtech spindles which are about an inch drop. Does anyone know if the will have enough clearance with the 5" backspacing and not hit the tie rod ends? Thanks for any help.
