window regulator for a 1969

[REDROCKER652002]

My son's 69 C10 window regulators are pretty shot. The drivers side is obviously worse off, but I a looking to gt both. I looked at GMCPaul and Brothers, they are both the same price, so I am wondering if either is better than the other. I have dealt with Brothers many times, and they have always been good, but GMCPaul is a member/sponsor here if I remember correctly. Also, how difficult are they to put in?

Any info would be appreciated.

Thanks RR
