Bethro has an M8. Completely different from ours and can’t be compared.

I have a feeling 2” would touch with my setup. You can mock fit the setup with a towel as a spacer between the tank and front head but your crossover line might be too short to extend the full lift. I had to replace mine but had the tank off for Rocker Lockers anyways.

 

You're right. I may need to do a mock up first and may need to go with a 1 1/2 instead.

Take care!

 

No issues on either side
