A lot of the eBay ones are lhd I have heard.
+1 be carefull as they will not fit.
Correct...when I had mine done, I went through 3 sellers and 5 manifolds from eBay before I got one that actually fits. Honestly, I would not buy one off eBay...save yourself the hassle and pay a little more to get one straight from a manufacturer. The one I got in the end was a SuperSprint one...even that only just fitted, required 1 person with a strap pulling it into place while a 2nd bolted it down. What a nightmare that was...all because of dodgy eBay parts. I reckon most of the manifolds being sold on eBay are either factory rejects or being sold BECAUSE they don't fit.
The bolt holes that are supposed to join up to the block just didn't line up, a couple of them as much as an inch out...and you try bending stainless steal pipes any more than a couple millimeters!
