1981 2" exhaust heat riser valve
Well I lost the damn thing somewhere. Took it off to modify it so it is open all the time, and lost it. 
Can I get a spacer for it, or do I need another 2" valve assembly?
Any 2" valve, or 2" spacer and the flat gasket and donut ring?
Thanks

Yes, I know where to get the riser itself, but I would rather put a spacer in; like this;

no emissions testing in WI, has no impact on performance, it's for helping cold start up and emissions. I don't drive it in the cold!

$5 part at any junk yard...whether it works or not. Just use a grinder or Dremel to cut the rivets off on the valve plate. Leave the rest as-is. It looks the same on the outside. 
It's a good idea to put the little 'block-off plates' in the intake manifold gaskets so the exhaust heat doesn't flow thru the intake runner, anymore.
