Wow - we may have a winner! I went on the Moss motors site - the exploded MGB column diagram is difficult to see, but from what I CAN tell, it sure looks very similar. The bushings are available, and with shipping were about $17.00 for the pair. I ordered them - for 17 bucks what the hell. If they fit, it's a solution to a problem I thought I couldn't solve. If they don't - hey it's only 17 bucks! Thanks so much for the tip. If we meet at any event, the first cold one's on me!
