Have Dellorto 27d But Need 29d

[m82a1]

I am putting the finishing touches on the motor for my 1966 Mark 3 and went to mount the manifold realized it did not fit the port on the motor. On closer inspection, what I thought was a 29d and matching manifold was in reality a 27d. It is a shame because the carb is a really nice early sand cast unit with the green tag and is in great shape. This is the carb and manifold for the earlier Mark 111 four speed bikes. So if there is anyone out there in need of this carb, manifold and really nice bell mouth and has what I am looking for, I would love to make a swop. Thought I would give this a shot before resorting to a long ebay search.

Any help is much appreciated.
