I think there's a typo in the crg report on 67 - 69 cooling, the quoted length of the 67-68 bb spacer is shown as 1 9/32", should be 1 29/32" ?
Martin measured that one for me:
3857042 body is 1 9/32" plus tit is 5/32"
Martin, can you confirm that dimension?
Rob, what is your measurement of the part?
Mine measures 1 29/32"
Mine measures 1 9/32" for the body. It has the part number cast into it. Does yours?
