Congratulations on your mgbgt!
Love the collor, realy seventies.
Could be because im from 74 myself and growing up seeing these great cars arround me that they give me that nostalgic feeling.
Im kinda fond of seventies car as, beside my 75 midget, I also have a 78 Jaguar XJ6 in: Morrocan Bronze!
Wouldnt worry about the bumpers to much and if you ask me I prefer the mg's bumperles anyway, they have the right curves for it!
Ive left of the rubber bumpers on my midget after ive mildly crashed the front about half a year after id finished my 3 year restoration...
What I would like to know if I was you is the condition of the bodywork behind the chrome sillcovers as thats usualy a dirt&moist trap.
