Where to get Hasselblad parts

Hello all. First time posting here! I recently picked up a cheap 500C which is a bit of a dream camera for me. Its overall in great shape, however the reason it was cheap is the previous owner had sent the camera off to a repairman who was supposed to swap out the screen. When he did this, he snapped off one of the screws and beavered up the screen frame a bit trying to get it out. He then apparently lost the screen spring. I drilled out the old screw (I tried many things to extract the broken off nub) and have a tap in the mail to tap the hole out to 1.4mm above the original 1.2mm. I would much rather just replace the frame, but am having a bear of a time finding one (the screen spring too for that matter). Does anyone know of a tech or shop that might have these parts and be willing to sell them to some schlub (namely, me!)? I included the exploded diagram. the parts I need are the frame, part #20955 and the spring, part #20976. Thanks for any guidance on who might have these parts! I'm seriously champing at the bit to try this camera!
