Brake Headache

[ChevroletWT]

If any of you have followed my build you will know that my truck was a complete basketcase when I first got it (And kind of still is). So my quest continues as I try to get things right.

The rear end is a 5 lug (1970 12 bolt), and the front drums are factory 6 lug. However, some lugs in the front drums were broken off, and after heating them up, and using a floor press (with the drum supported at every point possible) the metal around them simply gave without the lug coming out - so I am considering them shot.

Here is where I am now. Since my rear end is 5 lug, I decided it would be easier at this point to convert the front to 5 lug as well (it would also free up my wheel choices).

Here is the kicker, I have already rebuilt the front brakes and have some money put into them to do so. So I do not want to convert the front to disc.

My question is, what are my options, if any, to convert the front to 5 lug drums? Does anyone produce conversion drums? Would the drums off of a '56 Bel Air fit by any chance?
