i have a 2008 grand star newwmar 3305 it is a ford F53 chassis. I have not been able to find the serpentine belt replacement. the ford number is JK6-1107-A which is no longer available. all three parts place here have a different size description. i am to old to get under and look at the belt number but it is original. help if anyone has a replacement part number thank you
If age prevents you from being able to get under to check belt how are you going to install it? The shop that installs it will be able to source the correct belt.
