Passenger front arch loose?

[RKett 16v]

My 90 spec big-bumper arch on the passenger front side is quite loose and i've noticed that a number of the rivet style fasterners are missing and the holes that they push into are slightly enlarged. Can i pick these things up from a v-dub garage easliy or can something similiar be picked up from b&Q or a normal motor factors??

i got some from a little diy place. they need to be quite a big diameter so just get the fattest, short oned, and aluminium of course. the ones in homebase and wickes werent big enough
