[ballergwow]

Hi so I'm in need of some help as I got a Honda k series 6 speed gearbox for my k swap in a dc2 be here is were it gets confusing, I was told the box is from a 06 Honda accord euro so I jumped on it since hasport now has got a mount kit to use a accord or tsx/euro gearbox the egk3 but here is the catch my gearbox does not have the same 2 bolt accord bolt pattern for the egk3 kit it has a 3 bolt same as a egk1 k20 kit but still has the same egk3 crossmeber mounting sine there is no holes near the diff.

So what I would like to know what gearbox is this the code is SM5M is it a rare box? iv tried google and got jack shit nothing on it even with the code its a ghost box .

Is it possable that the gearbox case has been change to a k20 box,iv uploaded some picks to better explain sine this is so confusing

if any one knows or has info on this so I can move ahead and get the rights mounts would be much appreciated cheers guys
