Hi. We're doing a facelift in the bathrooms of our 50 yr old contemporary ranch. We'd like to replace the fixture on the tub, but don't have the money to pull out the wall and completely replace the mechanism. It is a three handle unit, and I'm not sure who manufactured it. Is it possible to simply replace the cheesy plastic knobs but leave the guts in place? We're looking on the web to find the replacement, what should we be looking for?
Thanks for the help!
