Does any one know which double tab is used on the lower rear part of the seat

medium or large? back of the seat rails bolt to it.

I have a few seats in the shop.
What would you like measured?

Length and width please

These only fit one way.
Big ones in the back smaller in the front.
If your trying to save money just buy the kit as you will need the small ones too.
