Wife and I stumbled across this place today while in Amarillo. While not a Hotrod shop per se, it does have a LOT of stuff of interest to a lot of us, IMO https://rvmuseum.net/ A fair bit of photographic history of bikes/racing/dirt cars and just generally a hidden gem Photo just because
Yup. I do believe you stumbled onto something there. More pics if you've got 'em. Their website doesn't seem to be particularly interactive.
