Swap pre-alpha drives - short shift throw problem?

[Mats]

Hi, thinking of exchanging my old and worn MC165 drives from 1968 with MC165 drives from 1976. Possibly the engines too (inline 6, 250 CID, 165 hp, swap from -69 to -76 versions).

Any drawbacks/problems I should be aware of?

Saw something about short shift throw, but is this a problem when swapping complete drives?

"1973 and earlier drives have a short shift throw and are not compatible with the 1974 and newer drives. So when replacing drives or swapping out gear cases. Keep this in mind."

Thanks.

Too tough a question?

Naw,..... Ancient antiques nobody deals with anymore,....

I believe you'd need to swap 'bout Everything, from the pulleys to the prop,....

I donno what the differences are 'tween the MC-1/ Alpha shiftin', 'n those before '73,....

Never ran into the situation before,....
