Have you tried DR Coffins on Witch Spring Hill in West Bath, Maine? I swear by them. They have done numerous repairs and are always willing to tell me when something DOESN'T need to be done.

My first experience with them was when my timing belt broke on a summer Saturday morning. they replaced it that day but the part was defective. It broke a second time halfway across the Carlton Bridge, in summer tourist traffic. They came and towed it off the bridge, browbeat the parts store for a replacement part, and stayed open into the afternoon to install it.

Great bunch to work with, honest clean and trustworthy.
