I needed some Delphi anti-roll bar rubber bushes for my LeBaron but the order was stopped by Rock Auto. Delphi was the only brand that would fit.
The customer service email is service@rockauto.com and I've contacted PHINIA USA(who now owns Delphi) and asked them to supply the necessary documentation to Rock Auto. PHINIA has been great and various customer service and sales reps are on the case.
Bit of a faff but it's a workaround if you get stuck ordering parts...
All the best.
