Ebay is a very good place to buy parts at a price that is just too good to be true. I've been ripped a few times where the item was priced in the hundreds! Man, that still hurts! I hope the seller will work with you on it. My Dale's insert was a very tight fit in the Brookville shell before I started working the shell opening and I am still concerned that the fit will still be too tight after painting. I am pleased with the Dale's, but the Dan Fink insert is in a class by itself. Making repro parts fit seems to be a part of building a street rod. Your problem seems to be a new twist on the shell/insert fit problem. Dang!
