@mxer20 got your eBay message. If you've lost the plates on the bottom of the chassis that bend the pick-up shoes upward, you are pretty much out of luck. Someone tried doing the metal 3-D Print, they have to be manually cut apart and it's a nightmare. The only viable option I am aware of is a donor vehicle. Back in the day, they had a Tune-up kit as seen below that was about $3.50 Retail! They are worth too much to open IMHO and very HTF!
