Folks,
I have a few badges on the front of "Tafie" see picture link below. I haven't noticed any problems with cooling and the car runs at the same temp whether the badge bar is in place or not -- I checked!!!!(sad, I Know

) Perhaps it is the cooling effect of the very attractive lower grille and air deflector I have fitted.

I would be very happy to have a TM badge Dave W's suggestion of the outlines of the Trad and Aero8 would be my preference
Cheers from a lovely Morgan day in Ireland
