Hi guys i used to have a westfield a good few years back and when lifting the bonnet off it had 4 tapered style pins about an 1 1/2 tall that located the binnet in position, these were pop riveted to the chassis rails, anyone kno where i can get these from to locate my indy bonnet to..

Not IVA safe but Rally Design sell them.

You mean the ones that locate the bonnet to the back edge of the nose cone?

Think I got the wrong end of the stick.

IIRC people have used lift the dot fastener pins for that job.

I've added some to mine recently. I screwed some threaded bar into an existing rivnut (to replace the existing screw that holds the battery tray down) then then screw a new rivnut on top, upside down. There are probably better ways, but that cost me 0 pence and no new holes
