He is a bit of a liar. Doing a bolt mod for $50 extra bucks, because the parts are "not inexpensive"? It's about $4 in parts, tops. I know, I do a lot of them. It does take a couple of hours, that part is true, at least.
BiNiaRiS, if you want it bolt modded, and don't want to do it yourself, let me know. We might be able to work something out.
