@solarixsy , Solarisxsy , That really is in rough shape. I think your best bet would be to try and find a good used parts machine on Ebay, Amazon,Craig list, etc., and transferring parts to fix. Duct tape is not a perfect idea, looks like some one already was doing this and it might hold it together until you find replacement parts. Find below a couple disassembly guides that may help when you get some replacement parts. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
