My turn to be a bit dumb, is this the cross member that holds the master cylinders / heater pipes and all that stuff?

I have one here and wondered how it differed from the heritage ones for example?

The reduced section on the Heritage ones is the deeper Mk4 type. The section changes below the speedo opening to allow room for the carburetor jet to clear.

When they added the wax-stat jet clearances became a bit tight so the pressing was changed.

Also the holes for the Hydro pipes were reformed to make the bolted joint and rubber bushes work.

The internal strengtheners are different between single and twin bolt frame mounts but I presume a Heritage one for a mk1 will be correct here. Well you hope it would be.

Thanks, really well explained - I shall keep my old twin bolt one safe then ;-)

Yes I'd buy one if they were available.
