Linn Sondek Dust Cover Hinge Repair

The Linn Sondek LP12 turntable I recently acquired had a broken hinge on the dust cover and wouldnt stay open. The other hinge spring was about to pop through. No wonder, with a steel spring rubbing against a thin piece of plastic. I got a quote of around $40 for new hinges that did not appear to be made any better than these, so I decided to fix them and put the dollars toward a better cartridge.
Ive seen other dust cover hinges designed like this so the repair could work with them. I drilled a 3/32 hole through the hinges and put a slight bend in the leg of the spring. I held the leg of the spring down and inserted the smooth shank of the drill bit through the hole. The excess bit was nipped off with a cutoff disc mounted in a Dremel tool. Now the leg of the spring is held by a metal rod.
The hinges were fixed but they looked shabby from the backside. I split an old computer floppy disk in two and cut some overlay patches out of the thin plastic case. Super Glue was used to adhere the patch to the back of the hinge.

My Sony turntable (PS-LX3) has the same hinges. I discovered a fairly simple fix for you do-it-yourselfers. Drill a hole on each side of the plastic portion just above the pin and insert an additional pin that retains the spring.

(Ignore the hole I drilled in the center of the hinge, that was a fix that was unsuccessful)

what kind of "pin" do you use?
