Sye, don't forget that the main bearings are non-standard sizes. The inners are 30 x 64 x 16, theouters 25 x 64 x 17 (original outer is made by HIC, type DG2564N-9, inner make and type unknown at present). Fortunately they are still available from Richard, but for how much longer? This could become a serious problem, so far I haven't found a replacement for either.
