I've done that once. Hurd sliding patio door used as the primary entrance to a very busy household (my childhood home, at one point there were 10 of us there, 5 were teenagers). The frequency was astounding; all of the moving parts, track surfaces, and weatherstrip completely wore out. Exact replacement parts were procured and installed far easier than complete replacement. If factory parts were not available I never would have attempted it. Just because a Dodge intake manifold will fit on a Buick big block doesn't mean it's a good idea. Tom That is what I meant. If it is an old Andersen slider, keeping the frame may be an option (of course to Kurt's point, depending on the condition). If the manfacturer cannot be traced or if parts are not available, it may not be an option even if the frame is good.
