No, there are self tappers in the heat shielding, from memory they are 10" or so apart all the way round. I assume you're talking about the heat shield?
That is of course, if someone hasn't replaced them with rivets.
Mine was riveted on-10 rivets,its only a 10 minute job to drill them out,dont think you will get at prop any other way.While your at it dont forget to grease both UJ,s,there is a grease nipple on each one.Its about a 20 minute job to rivet shield back on.
