59 camino

Hello to all first gen camino folks. I am restoring a 59 elcamino. I want to put it onto a frame with p/b p/s. I have a 77 Monteo carlo frame under it now but the fit is poor. Does anyone know a better match oof frame for this car as the original frame is history. Thanx a bunch. Kelcamino from BC Canada. :banghead:
