Better have your rear splines dead nuts if you have a spool in the rear..
a way around that would be to drill the axle bolt holes oversize, then use flange nuts with large, grade 8 washers to attach the stands to the axles. this would not affect strength of the stands, nor the attaching point strength.
The nascar example only shows two lugnuts. I dont think you need to build it for the full lug count
Shear off the upper lug half of the bracket, and use it upside down on the lower lugnuts.
You would only need to oversize the lower holes to allow for spool setups.
(Hope this makes sense)
