Frame

[SwitchbladeII]

I am in the process of restoring a 1957 Step Side (not to stock) Due to what I want to do and what has to be done to the frame, I am considering going to a TCI frame. I am looking for some feedback on TCI and open to suggestions on other brands. I found a five year old forum were a user had some issues with TCI. I hope to hear from someone who has purchased one recently. I am concerned about the predrilled locations for cross sills and bumper brackets. Since the frames are boxed treaded inserts have to be welded in and in the correct location. I don't know how bed bolts would be tightened. I will be calling TCI and possibly a few others but always good to get fellow gear head input! Thanks in advance!
