Technical Uno seat removal

[UnoMia]

Hi,
Can anyone please advise on how to remove the front seat from the Uno 2 door model? I know there are four bolts at the front seat support to undo but the seat is then still held by the two bars under it and they appear to be rivited to the seat slide rail. I'm sure there must be an easy way to remove the seat as I can't immagine it was designed to never come out again!
Thanks for any advice.

There is a pin in slide rail that you have to bend

Covered several times before - try a search

Basically there's a tab in each seat rail that you need to knock in with a drift (e.g. a socket extension or BIG screwdriver) and a mallet.
