I have this one, and it works pretty well.

Do you know off hand what size those nuts are?
The package includes some various sizes

On my 250, the subframe used 8 mm inserts, with 10 mm bolt heads.  The side panels are 6 mm inserts, 8 mm head.

My 97 500 uses 6mm bolts on seat and side panels to sub frame. You can also by the rivets themselves from an OEM parts distributor but you still need the tool to install them.
