For elevation the "bubba" trick is to strip some insulation off 12guage electrical wire, warm it with a Bic and sleeve it over the front post. Let it cool and shrink, then cut/file the insulation to height at the range.
Avoids replacing the front post entirely, and can be undone easily enough should you decide to start shooting with the bayo attached (which is how it would have been zeroes initially).
edit: Uh, that might be 14guage wire, can't remember.
