Seat Runner

Morning all
So my '73 rhd LB
I have replaced the drivers seat tub with a Schofields replacement.
I have removed the seat runner from the old tub and went to fit to the new tub.
The tub surface is flat and as per the picture the runner has a step shape.
Any ideas what others have done?

Thanks in advance

Exactly the same situation as mine. The old tub profile is a little different to the newer style, and the old runners aren't compatible.

Luckily Butty's bits will sell you a flat runner with the old style teeth (https://www.buttysbits.com/product/...drivers-seat-runner-specials-see-description/):

 

Hammer ?

 

I did think of that, maybe use the 10ton press at work though : )
I just thought it strange that it was so far out though.

 

The post 1976 seat runners also expect a flat base, so the tubs match those.
