Actually, the aftermarket replacement kits are getting better all the time and we have a member, Bob Dillon, who rebuilds/modifies old UIMs in a manner that should
prevent or at least seriously delay any future failure.
Additionally, the LIM gasket failure can now be eliminated by using the newly available GM aluminum-framed gaskets for about $60 at your local Pontiac dealer.
Costs will vary for the UIM replacement kits and all gaskets and seals, depending on which one you get and where you get them.
