This is great - thank you all so much for the parts info and close up photos as I am about to do the same thing with a disc brake conversion and replacing my control arms & front cross member due to rust.

Question : When bolting back on the (‘new’) front cross member : do you use a washer on the bolt head side (it appears GM didn't originally) and on the other/nut side do you use a 'washer/ then lock washer/then regular nut' or do you use a 'washer and lock nut' ? What do you all do/suggest please ?
