aye - i can get hold of some metric taps no probs, and u are right regards the hole spacing and size etc, couldnt let them go at 50p tho! they are a lot more substantial than the cen 21 mounts and should help with the chassis flex when i hit the throttle...
hmmm i havent forgotten the last incident... ahem... i will use the beach in my search for 2nd gear i think... oh it wasnt a tree by the way - it was a large bill board advertising a miniature railway... i did dent it quite well tho...
