Hi. I've got 6.00x6 Aero Classic Tubes, Short 90 Stem TR-87 tubes on my RV-7. The right one has a valve stem core that needs replaced. The center pin won't always kick back out and seal after checking pressure or adding air. The pin kicks crooked and I have to use car keys or something handy to get the needle back to straight. Then, there goes the air. Once the pin is correctly seated, it holds pressure. Have removed it and see no damage or FOD. Does anyone know the correct valve stem core to replace this? I tried Desser and they had no information and do not sell the core. ACS has several to choose from with varying lengths. Any help is appreciated! Thanks.
