My 1968 18 2 plus 3 classic made it to Florida and back to Iowa. I had put about 8 ours on it when the outdrive decided to lock up. We pulled the drive and the upper and lower gear sets seem to be shelled. So my mechanic feels that our best option is to find another outdrive that is in good condition rather than to go through and rebuild the current drive. Any thoughts or ideas on how to proceed? It is the original Holman Moody 302 Ford with the Volvo 250 outdrive. I am thinking it is the 1:61 gear ratio. Would a 270 drive work in this application? Appreciate any help!
