I purchased a wiper transmission for the 54 and installed it today. Unfortunately, The cables are about 3/8' too long. The tans out of the 54 has a screw in the end whioch can be loosened and this causes the ratchets to work.. The trans I acquired has staked ends and I do not know how to adjust it. The supplier says all bodies from 54 to 56 are the same and this is what they sent me. Any thoughts would be welcome. Jim Buick
