I looked at the Thompson from CRC and they only have one inline post at 30.8. I wanted with layback.
I found a 30.9 Truvativ T40 for a great price. Ordered that and waiting for it to come in.
Cross your fingers
How did you know it takes a 30.8 in the first place? It seems odd that either will work.

Why would a larger post fitting in a smaller hole easily mean that it is too big?
