I've dealt with them a bunch over the years and here's what I've learnd:
1. They wait until they get enough parts orders to justify the cost of switching tooling on the stamping machines. Sometimes that's two weeks or ten months.
2. The admin/sales staff really doesn't know what plant operations is doing or planning.
3. The admin/sales staff doesn't know what's been posted on the web site until you remind them and they go look at it.
4. They are pretty much our only source for these replacement panels so be nice to them. MSA, VB, and any other vendor selling replacement panels for the S30 are buying them from Tabco. That includes the rust repair web site listed above and most every eBay seller.
5. When you order stuff, order extra and if you don't need it, put it on eBay.
