A part of the repairs after the accident was to refurb the new-to-me bumpers,
specifically the rear, where one of the rubbers was hanging off.
I'm sure there are other ways, this is how I'm doing it.
The original steel inserts corrode and break/fall out. I removed all the old
bits and what's left is a circular slot with a flange within. I got some
stainless bolts and washers, mig'd them together, and with a little effort,
they push into the slot. Most of them are tight, and although would probably
work as is, I'll put some SikaFlex on top to make sure.
The other issue is that this centre section has shrunk in length by about 25mm.
This may be a challenge, not sure how to pull this yet.
