Harman p 68

Needed a distribution blower for my p68. All local dealers were taking about 2 weeks to receive. Ordered through Stove &Grill received in 3 days. Everything is working great. Thanks


Shipped quick and fits perfect!

Great Customer Service

Had a defective blower motor and a replacement was sent out right away with no questions asked. They didn't even want the bad unit returned. Will definitely be buying from these guys again!
