HELP! Having problems fitting Dinan plenum spacer... - The Unofficial BMW M5 Messageboard (m5board.com)

I recently purchased a Dinan plenum spacer from another board member and was supplied with bolt extensions to accompany the studs. I am having two problems right now, One I was supplied with only 11 extensions all of the same length and 4 black cylinder pieces(my guess those are for the 4 studs in the center) and a unique extension for the single stud closest to the front of the engine, problem being there are more then 11 studs. Problem two, the 6 studs furthest away from the front of the car are different lengths then the 5 in the front. So when I install the bolt extensions to the 5 in the front they work fine and sit flush with the spacer, but when I try to install them to any of the 6 studs in the back they do not sit flush with the spacer. Does this make any sense?

Question:
1. Are there pieces missing? I.e. different length studs for the rear, and special stud extensions for the center 4.

I am currently driving around with no velocity stacks because they do not fit with out the spacer. Any help is greatly appreciated.

Thanks.

the dinan velocity stacks do fit without the spacer. I have the stacks and larger throttle bodies, but no spacer (dinan d/c'd the spacer long ago). What kind of velocity stacks are you using that don't fit? If they're dinan, somthing is not right.
I'd either call the seller if parts are missing, or call dinan.

When Dinan d/c'd there spacer they redesigned the velocity stacks to fit without the spacer. They are larger in diameter and height then the revised stacks.

I guess I will give them a call and see if i can get them to give me a part number or see if they have a set laying around.

Thanks
