Spindle help please

[Thealien]

I purchased the QA1 front and rear suspension for my Blazer build.

I plan on using the Willwood spindles and brakes eventually. The Blazer is going in for body work and paint sometime next year and I do not want new wheels installed during the body work and the stock wheels will not clear the Willwood brakes.

The QA1 front suspension comes with the 1973 and up ball joints and will not work with my stock spindles (and I don't have a reamer).

What spindle could I use that would work with my factory disc brakes and fit the QA1 control arms? If possible I would like a 2-2 1/2" drop spindle so it will match the Willwood spindle I will eventually go with.

I am OK with used if anyone has anything.

Thanks
Mark
