    Comments about CARQUEST by Dayco Poly Rib Belt:

    Bought this for my power steering unit for a JDMH22a swap.Turns out, the motor was different than the specified year when i was buying parts for it.So the belt didnt fit at all and came up short.Sadly i lost the statement with the RMA stickers so i cant RMA the 2 short belts that i bought.[...]
