All-Crop 90 Straw Racks

I've had my 90 sitting in a shed unused for years. I bought it to compliment my 66's back when I was a huge fan of the all-crops. Since then, and having been around several other PT combines, I'd become less enamored of the all crop design and had been hoping for a decent Oliver 18 to come along and scrap the 90. This weekend, however, our plan to have  a neighbour combine a few acres of oats fell through when his combine broke down, so I dragged out the 90, did some hasty cobbling, and used it for the oats. It worked surprisingly well, given how rough/beat up it is, and I'm now thinking it's worth putting a little more time/money into. Most of the rusted/worn parts I can have made by a local fab shop with a plasma table and brake press. Other parts I already have spares of. The straw racks, however, are really, really rough, and I think it'd be too pricey/cost prohibitive to have them made. Many of the bars are broken/bent and I screwed/wired them to some chunks of hardwood to get us through the weekend.

If I could find a set of racks for this thing, I'd probably slowly work on fixing/restoring it.

   Second, I am looking for a part(s) for my All Crop 72 for the separator drive assembly on the rear of the machine. Are you parting out any of your other All Crops? A 66 or 72 model would be the same for what I need. You can contact me about either of these.
