Personally I like the screw/bolt/rivet down look and I had to get a bigger scoop when I changed engine.
Fortunately, Doug Pearce makes one specially for RMC's - I dont know if he does Classic Revivals but it might be worth a call.
went from this..
to this..
I like the style/look but now I have to match the paint...
So, if, like Phil, you think that you'd prefer a different scoop then getting it now is definately the go.
