You got it. Of course, you could move the lower ball joint outward as well. Whether you could move the upper ball joint inward enough with just alignment, I don't know - so you might need custom upper control arms.

Which off the shelf ones are you going to get? Which hubs and bearings do they use? Which suspension analysis are you using to zero in on your geometry? Sorry for all the questions, but this might be something I'd like to do for my 2nd gen f-body.
yes, those are the basic style of spindle, dennis will have to chime in on which one he is gonna run. mine use a GN style snout, and a winters forged hub with built in rotor carrier. i looked at all the different options to see if i could use an off shelf item, but nothin fits my 1 off design even close, so after researching the build process, i decided to build my own.

i have more time and money into my modular jig than expected, but i can build my spindles and make design changes if needed in no time flat.

I am running the Impala 9" version. It uses a full size ball joint taper and full size wheel bearings/seals. For a budget hub I am going to cut off the rotor hat from a pair of full size rotors and machine the hub OD to fit a generic rotor hat.

Thanks Dennis. I can see why you'd choose that set of options. I've tried to find engineering drawings for those spindles - have you found any? King pin angle, king pin height, steering arm length and offset, etc?

King pin heightThe spindle pin is at 3.75" measured from the bottom of the LBJ mounting boss

Steering arm length steering arm length is 6" center to center EDIT, checked the arms again today; the left arm is 5.5" while the right is 6". Calling tomorrow to see about having a r/s arm built with l/s length
OffsetAckerman is zero
Anything else?

They look exactly like mine.

Are you running the offset length steering arms Sideoiler?

nevermind.... had my head up my a$$ again, i was thinkin wide 5 style fabbed spindles where the lower taper and steering arm is welded into the upright.



so if i was to use the impala style spindle with gn snout, then the winters hubs would work..... right?

im thinkin i could possibly run the off the shelf impala spindle, and adjust the r.c. with balljoints to get back to the same point as with custom spindle pin height.
