preassembled sections and I don?t to do these one at  a time at crane rental
rates.

Klein Tools and  SteelErectorTools.com offer some really hefty ones for 
steel
construction,  and I?ve found little drift punch sets at Sears and Ace
Hardware and Harbor  Freight, but not one that?s about the right size for
this. I think a ??  point diameter would be about right, maybe the large
diameter would be ??,  perhaps 6? long?



I've always gotten mine at  Sears. You have to grind down the point a 
little for the 25G small leg bolts but  other than that they work FB.
