stupid question time

[manic]

. i have had some one spray a shell for me for a vega 4.1. i brought the car with out a shell. the one i have had done i think he said its for a c4.1 so not a purfect fit
how ever after cutting out and get it seating properly(ish) what is the best way of keeping it on. as there is no body clip points. i was looking at useing the ones out of a pred x11 and tapping the chassis and cliping threw the side
or is velcro an option just wondered what other people have done
