Hi. I've searched through the forum for mention of what length the Rawlnuts used are. I only found one person who mentioned that there are different lengths.
Having searched through the parts manual, I find that all the M5 Rawlnuts have the same part number (A075W6074F), so I assume they are all the same length. All the M6 Rawlnuts have the part number A075W6140F, apart from those for the oil cooler, which have the part number A082W6285F.
Can anyone tell me the the lengths of these three fixings?
In all, I counted 27 M5s required and 20 M6s required, of which four were of the different part number.
Does that all make sense? Have I missed anything out?

i dont know their sizes. but i will genuinely warn you that in my experience.
i have purchased a assorted kit of rawlnuts with all different sizes. and none of the stuff that came out could be replaced with a rawlnut in my experience. it didnt matter if i put something bigger or deeper (or both) that what came out. they always ended up spinning for some reason... so... against the advice of the folk from the forum. they were all replaced with rivnuts.. and 12 years on. the rivnuts are still holding well.
fitting rivnuts is ricky tho. as the amount of pressure to get them right is an aquired skill, too much and you crack the fibreglass, too little and your nut is spinning.
the nice thing about it is that you can add more pressure in small increments untill it feels tight and before it cracks.
