Outer Tie Rod Question

[astroracer]

If you check out my Bad Ast thread (go to the bottom of page 11) you will see I am modifying the steering arms on a pair of dropped Astro spindles.
A little info:
In order to work with my suspension design and Corvette rack this is where the outer tie rod point needs to be. For wheel clearance I am also flipping the tierod over so it points down instead of up. This will either require me to machine a tapered sleeve to use the stock Corvette tie rod OR I could drill out the spindle for a 5/8th's bolt and run a Heim End. I kind of like the Heim End solution as it would also let me do some adjusting on the bump steer if I need to.
Any thoughts or concerns? I know the taper would be better for the joint but is there a real issue with running a straight bolt?
Thanks for your time
Mark
