Dave and Arthur.
Thanks for your advise regarding this. I’ll get the hair dryer out and see if I can persuade the carpet to loosen its grip! I’ll get some spray on carpet glue too,
I did manage to get my finger into the A frame plate on the passenger side and on that side there doesn’t appear to be any nuts.
I’ve also ordered a 5/32 socket Allen key so that I can get good purchase on the bolts!
Looks like it’s going to be a mid-week job!
