Bent mechanism on seat slider

I've bought some replacement seats, the passenger seat will not move backwards or forwards, on closer examination it appears the mechanism is bent thus preventing movement. My question is there a way of transferring the seat base mechanism? There doesn't appear any way into them. Failing this it's a trip to the garage to see if they can bend it back into position.

Hi Respace,

Bent in the bar you press to release the seat?

Or in the seat runners? Undoing the seat by the four anchor points and removing it allows you freedom to access.
