my buggy has (on the rear swingarms), a pin/bolt, which goes through the centre of the bushing on the swingarm, and screws into a housing. It has a large hex key type head (17mm hex/allen key head), and 2 large washers (one on either side of the bushing). I'm after some pins and washers, so if anyone has any they are selling, please let me know ASAP. I had to cut mine off, they were so rusty, so need replacement ones to put it back together....

Cheers

sounds like you talking about the IRS attach bolts
