I've had to cut a few of the bolts in the boot when getting the rear clam off, now all thats left is a bit of the tread and the rivnut itself, which in a few cases seem to spin freely within their hole.

Bit stuck on ways of getting them out for a kick off, so any input would be appreciated, and also if someone was able to point in the direction of suitable replacement rivnuts it would be fantastic

Also, was thinking about using this method for insertion of new rivnuts....

Angle grinder off the remaining stud then drill off the head of the rivnut. New ones from here:

I put steel ones in mine.....I think. Careful with stainless as you dont want galvanic corrosion.

Excellent! But there appears to be an awful lot of different type on that website!

Was thinking these?

Following on from this, is there a way that a few captive nuts could be welded on to subframe?

I have a rivnut tool I bought for just this job when mine were all knackered. I'll see if I can find it tonight. Think it was only £15 ish on ebay to be honest.

You could do this but you'd have to strip the galvanising first. Probably best to braze in the new nuts so that could be swapped out if the threads strip. Then you'd need to regalvanise the subframe. It would be a nice touch but it's a lot of effort to go to.
