Hook Bolts for Vendo 39 Evaporator

I am re-restoring my Vendo 39 from the first year of production (1949). When I looked at the evaporator, I saw that the bracket for the fan was attached to the evaporator tubing by three hook bolts. When I took the nuts off at the end of these bolts, two snapped because they were corroded. I wanted to replace these parts anyway because they are made of steel and were rusty. Rod at Fun-Tronics showed me the other day how his son replaced these hook bolts with screws and fender washers that rested on top of the evaporator fins. I considered doing this also, but then I found another way. I was at my local Ace Hardware today and I found #6 x 3" stainless steel threaded rod. I bought three of these and modified them for my machine. First, I ground the threads off about half of the length. Then I bent the rod to approximate the shape of the original. The rod was fairly easy to bend. I didn't match the original shape exactly, but I got it close enough to work. I like that the pressure is on the tubing and not on the fins. Attached is a picture of the original hook bolt (on left) and the three hook bolts I made.
