Mic, for a clamp, I'd order a black aluminum Torque clamp from Mystic- they look great, economical, have no logo, and most importantly are slotted so you have some wiggle room on the spacing. I use SS screws secured with nylocs, cut to length, and the stock Penn capture nuts. Works great. Just double check your distance on centers, but I have to imagine that clap will fit.

Excellent advice John,
I'll dang sure look at those clamps and the nuts.
I think these two old reels will not only be strong and tough, but look cool as hell doing it !
