Front spindle identification

[my56chevytruck]

I'm not sure if this is the proper forum for my question, but here goes. I have put on 2" dropped spindles to my truck, but I'm not happy with the issues of tire to fender rub and a bit of a BANG to the front end when hitting a bump so I'm thinking of going back to standard height front spindles. I've got a pair of spindles with casting numbers that I cannot for the life of me find any info on the internet telling me what they're off of.
I have a 2nd generation Camaro front clip and the (2) spindles I want to install are:
329353 LH and 329354 RH
Will these mount up correctly to my existing front suspension. I thank you.
