This is a rare, 1958-only, split style rim used on Triumph TR3s, as well as Vauxhalls and Austins and other British cars of the period which we are less familiar with. It is in mint, new old stock condition, in its original packaging. The Lucas part number is 552913.
We also have a decent used rim like this one, priced at $55.
We also have several pairs of new reproduction and NOS headlamp rims for TR3s of other years. Please email us if you don't see the listing on this website.
