Hi,
I bought a pair of bumpers from Harringtons for my ‘63’ Flavia Coupe back in 2016. I’m very satisfied with the quality of the product. The fit is very good. The rear is a little more tricky to fit than the front, but on the whole not too bad, just a bit more patience required.
Thing to remember, stainless steel is never quite as bright as chrome and it does scratch very easily. It’s not cheap, but in the long run, I think a better option than having the old ones rechromed. I actually only needed the front but managed to sell the rear, which recouped some of the cost.
Good luck, Peter
