Should be fine mate as far as i know....although new seats don't come with guts
This being the case, I've had some probs myself with the old-style guts not fitting the rails properly. Could end up with a seat like my Free Agent one, where no matter how tight the bolts are, one hard knock downwards and one of the rails dislodges, then the whole thing's loose again.
There might be better guts around, but my local outlets don't sell them.
