The thing with pre-64’s is the area around the rear guard screw. Dropping a pre-64 into a stock pattern designed around a post-64 action often results in the bottom metal protruding 1/8 inch around the rear screw. Inletting it deeper will not help ... it’s a difference in bottom metal dimensions in that specific area that requires more material to properly accommodate the pre-64 bottom metal.
Obviously, the pre-64 Montecarlo is designed around the pre-64 and thus fit is perfect.
Heads up ...
"What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as freedom should not be highly rated." Thomas Paine
