Drop spindle differences by brand?

[Houston Ben]

Hi all,
86' C10 stock 15X8 rally, Looking at 2.5" drop spindles (1" rotor) but most searches come up with 67-72 trucks. I have seen posts that say drop spindles push out the wheel a little, is this just on 67-72 or all? If this is the case, what brand will move them the least? I emailed CPP but they told me they don't manufacture spindles for the 1" rotor.

I found Western Chassis spindles for 1" rotors on Summit, but at the moment the price is $603, no thanks! I have an email in to see if this is a typo.

Any other suggestion I should look at that won't affect the track width?

Thanks for any input.
