HP 5000 and 5100 duplex unit parts compatibility

I have a bunch of HP 5100 DTN printers, and 2 of them are missing a front duplex unit tray. Without the tray, duplex can't work, also printer gives an error and would not continue.
I can not find anywhere this tray for purchase, so the only option is to find a broken duplex unit. I know that HP 5000 and 5100 can't interchange duplex units, so my question is: is the front tray same on both models?
HP 5000 duplex is much cheaper to buy (around $120 on eBay).
I would appreciate your help in this manner.
Thanks, Ned
