I'm trying to get together all the bolts needed to get the TR3550 installed in the car and I'm missing a couple of the shifter bolts. I don't have the transmission here so I'm not able to pull one out to measure, and the only information I could find online was for a T5. The Hurst shifter instructions mention 5/16" bolts, but nothing more. The T5 are metric M8x1.25x20mm. Anyone know off hand what size bolts I need to order?
