Hi Peter!,
....well, THANKS, that would be fantastic if I could get the measurements to use!! And, I'd just be re-using the Mk II FH, so no problem there.

On the provided picture.....doesn't that barrel for sale there @ APEX, show that the front end is already profiled and notched for a FH??? What am I missing....??

Of course, the real answer I suppose is to get in the car and just drive down to APEX and pick one up and look.....not that far away from here...
