Yeah, I just went all through this but can't remember what I ended up with...a couple things I can tell you. Lester apparently had different standards for different rim sizes and/or models and/or changed throughout the years...so if it worked for someone else, does not mean it will work for yours...at least 3 different diameters and at least 2 different lengths required. My 18x3 rear and 18x2.5 front required 2 totally different valve stem lengths and diameters. I did manage to scrounge up 2 stems that worked in a matter of a couple days, 1 I had in a collection of car parts, the other was found at local mega dealership, that I would never allow to touch my rims or tires. Good luck.
