Ive got a 1/2 inch MD plenumspacer brand new and still in the fed ex packaging from the company. Im selling this one because ive decided to go with the 5/16 as well. I'll give up a few ponies i know, but it was my mistake buying the wrong one in the first place. Ill take an even trade if youve got a new 5/16 with gaskets and hardware not used. Or sell it to you for the price of a new 5/16" plus shipping im guessing thatd come out to about 200, my loss your gain. email me at
paulokeefe07@gmail.com or IM me at monkyparts...thanks!
