I have already checked with the RIN locator. You’re right. VE is rare, but I found two matched tanks NOS.Yes and @tursiops posted a link to a facility in Lubbock. Or the OP can check the current PHMSA list here: Cylinder Requalifiers | PHMSA
There are 621 requalifiers in TX alone and dozens in Houston so the right way to do this is to search by zip code and call them. But as mentioned, shops are unlikely to fill a 6351 cylinder anyway and they are at least 33yrs old at this point. It's highly unlikely that the value of the cylinder is worth requalifying +VE at this point.
