Heeeelllp!!! In the process of fixing a major leaking problem with our kitchen faucet, I managed to create another major problem -- broke the hot water (left hand) valve stem. Tried to tighten it down too hard with the screwdriver while re-assembling the faucet: >snap!< Of course we live in the middle of nowhere, 100+ miles to the nearest RV parts store. And I'm not familiar enough yet with the online sites selling parts; so could anybody recommend or give me some hints on where might be the easiest place to find/purchase/order from? I'm just looking for the (plastic/pvc) valve stem - not the entire faucet! not sure of the make/manufacture of the sink/faucet assembly. It's from a 1981 13ft Sunline - not sure the model. If someone can help me out it would sure be appreciated! Thanks
