I can not express my gratitude to both gentlemen I dealt with at Custard Core Supply. Their customer service was outstanding. I eagerly anticipated my order arriving, and when it did, my high expectations were more than lived up to.
The product was packaged carefully, and it was so clean that it looked brand new. Wow !
I noticed this company is on ebay. Normally, I am very leery of ordering anything on eBay because there are so many fakes and imitations. Custard Core Supply is one company that I would order from on eBay in a heartbeat - without hesitation.
I hope to make another order very soon. Thanks again gentlemen.
got a crankshaft and it was exactly as described great packaging i will absolutely purchase again…..also the customer support was spot on 5stars for me
