Any body know the bolt spacings on these bindings, There are a cheap pair on ebay

The UNION binding without laces and just that elastic wrap, great entry level boot, is a 6.5 and i think 7 inch spacing, this means it will fit on most boards... but im not too sure on the 7inch thing...

Yeah Charl is right but I think it can fit even wider than 7 inch. Because of the base plate of the Unions it has almost another inch of adjustment (give or take a bit), dependent upon which hole you choose and where you screw it into position on the other side.

Also depends which year model you are looking at. If you know the year PM me, I'll measure up for you.

k iv sent a email to the seller asking the year. does anyone have any experiance with these bindings any good any bad?

They're a good boot to start with. Pretty easy in and out, but most modern boots are these days. Fair bit of flex and very comfortable. You won't be disappointed in them, and as you progress in boots you can decide whether you want a stiffer pair in time.
