If it's the bolts on the downpipe he's worried about they may be re-tapped to a larger size, I had to do that with mine, brittle metal but it can be done. BTW waiting 4 weeks for wheel cylinders? tell him about a place called Rovers North, I was able to get my wheel cylinders in 2 days...but maybe I just got lucky!

If you need to feed your Land Rover Jones why don't you come out to MAR anyways, believe all you would need to do is pay dues and sign a waiver. Then you can hang out with very knowledgeable Series owners (I'm not including myself in that group) and learn. I'm sure you would get plenty of offers to ride along as we could always use another person to help push.
