Hi can someone help, Ive bought 5 15" MG TF wheels which I want to fit tom my recently bought TR7, the thing is the centre cap is badged MG and as its convex, it won't take a Triumph decal as it needs to be flat, can I modify or where do I buy blanks, needle in a haystack stuff for me as I have no contatcts, its a minor thing I know but I am into quick wins at present before I start improving the condition of my car. Another wee query can I fit a more powerful caliper now that the wheels are larger in diameter. Thanks in advance Robert
