i am looking at aanother short set like the one you have on ebay... but i dont have that fitting on my manifolds that goes to the bottom side of the riser... what cam were you running. i have another thread in the Q&A section wondering if i can run these.

they look more like what im used to seeing.. so if i buy them now you ship free? these are the others im looking at 290291661469. my manifolds have holes for the fitting that goes under the riser... would you include those fittings also?

I will be home by 4pm and will look at what you are referring too. Or call me 6092264485

I actually need the fittings but they really don't look like anything special that a general hardware store would carry.
let me know what else I can answer .

I just looked at the other set that you are considering. I've actually have never seen them w/o the provision for the fitting. They might be a different application like Dry vs. wet.

I'm sure another member here can help to give you the answer.
