How to make an easy-swap seat?

Hey guys, have a quick question. A long time ago I saw someone posted instructions on how to make a very quick swap for the SDR and standard seats. I've been looking for it here but I can't seem to find it, and I'm out at sea right now and the internet is pretty slow. I vaguely remember someone fabricated a new seat pan plus a universal tail light and swapping seats was as easy and switching them out and bolting on/off the respective body panels. Can someone post the link on here or point me in the right direction? Again I tried searching but my shop has 4 computers to share for 30ish people and whenever the internet is working its pretty slow. Thanks as always.

the thread you looking for?

No I've seen that one, but thanks for looking. The post I saw was someone who had come up with a true quick swap for the seats, like 5-10 mins top if I remember correctly. I remember seeing that post when I purchased a standard SD seat but now I can't find it. I could always use the link you gave me to swap seats though, it would just take longer.

Delved a bit deeper one?

990. There isn't a simple swap over. Not really. The single seat / SDR unit requires a totally different tray under the seat. There's a few people who have devised a way to swap from two to one riding but it not easy or simple.

Sorry but there isn't a good answer to your question.

There was a guy who was working on a quick swap, but I have not seen any of his post as of late. He went by Evilwork or some thing close. His avatar was the guy in a straight jacket. The guy is in Mexico. He hit a cow at night and was rebuilding his SD.
Anyway he was remaking the seat pan to accommodate both seats. He had photos of what he was doing. I was cheering him on, but we never saw the finished deal.
I searched a bit, but no cigar. Hopefully others might find his post, because he was on to something, tho looked a little rough.

one shows him making an under tray for the mod, but can't find the actual how to.

Evilwerkz hasn't been on since October either.
