If anyone knows CT law, it will be him. Tell him that Rick Dotterer from the CCRE told you to call. He will set you straight. Yes he is a body shop, but he is a consumer advocate for the individual car owner. Not a run of the mill, "get em in and charge as much as you can" type shop.
Yeah you need to find a driveline specialist. Body shops replace whole parts, straighten frames, do bodywork, & paint. Driveline specialists rebuild transmissions, transfer cases, driveshafts (and balances them), and rebuilds rear-ends (differentials).
