I'm working on it but I'll have to spend more money up front, at the risk of getting banished...LOL. The only way you can figure this stuff out is to buy up any and all manifolds that you think might work. At one time I had over 11 different manifolds and I didn't get one for free..If only I owned a junk yard!!! And when it's all said and done somebody (me) gets stuck with a bunch of manifolds that don't work!! You can't tell if something will fit or how big the hole is by looking at a picture on ebay. Anyway I'll tell everyone tomorrow how I got this manifold with the extra large hole unless somebody figures it out first. There's a BIG hint in one of my first posts about the manifold so it's not as secret as it seems. I thought for sure someone would catch on. Ya'll are gonna say "Oh yea, we knew that!!". It's all good, I enjoyed doing the research and hopefully I'll break even (moneywise). I'd have to sell 4 or 5 of these to even get my money back so I'm not ripping anybody off. I mean how many of you out there would be willing to spend $300-$400 on a bunch of manifolds that don't work...I did???? RRR got pretty close, he doesn't even realize how close...
