bolts for rear seats?
 

i need a replacement bolt for the drivers side of the rear seat cushion. the botl that goes through the metal clasp onto the cars chassis. anyone know where to source on from. theres supposed to be one either side holding it down, but ones missing, probably lost when i had my suspension fitted at scoobybits and the rears had to come out.

anyone got one spare, uk 99 classic. if not expensivo item from dealers?
