Mono to dual shock conversion (Who's done it?)

I know I have seen members converting mono shock swingarms to dual shock.
I have a 1995 GSXR 750 suspension, but not sure I want to go mono.
I've been trying different search terms for the last hour to find pics and info on dual shock swingarm mounts, but I'm not having any luck.
Could someone please point me to these threads or pics?

Thanks

Done it with 83-85 ZX750 swing arms, but never with a GSXR.
Z1 Enterprises has the brackets.

Don't think I have any pics, but I cut off the bottom dogbone mounts and welded them on top as shock mounts. Worked out well for me :)

I wanted to see what it would look like and thought someone might have already done it with a GSXR swingarm.
If I could do photoshop I'd already taken pics of testarossa's blue 78 KZ1000 with the 1995 GSXR 750 suspension

and added a different styles of sport fairings, chin scoop and shocks, to give me a better image of what the end product will look like.
I really like the look of my old 78 LTD

P.S. I was just getting ready to P.M. you back anyway. I'll get you the info you need as soon as I get a chance to go look.

both are awesome looking bikes.

the overbraced arms like testa's presents some interesting challenges when trying to dual shock one.

a busa arm with the upper brace removed and an underbrace added would be ideal to dual shock a kz with.
imho,

Leon,
I've thought about the GSXR overbrace problem and that's part of the reason I wanted to see what others might have done, before I told my idea and was thrown under the wheels of the bus.
I took a good look at the GSXR swingarm and see no reason I can't flip it 180 degrees.
I'll have to switch the brake caliper mount and chain wear guard (black nylon piece) to the other side.
The overbrace, would now be an underbrace.
Try to imagine testa's bike.

With the swingarm like this.

I even looked at the ground clearance and it looks like it should work. It doesn't look like the bracing would hang any lower than the underbrace I put on my 1978 LTD.

I have a '94/95 Gsxr750 arm on my '89 Gsxr750. If I recall correctly the arm is not symmetrical. I think the left side bows out more for chain clearance than the right side. Plus the caliper bracket is "armless" so you would have to weld a stay of some sort onto the arm if you flipped it.

There was a non-braced Gsxr swingarm in the classifieds at one time that could be set up with the same wheel fairly easily and the bracing wouldn't be a concern.

Later, Doug

Doug,
I'll look at it again and measure it, but it looked pretty symmetrical to me. I didn't notice any difference when I put the chain rub pad (black nylon pad) on the other side, when I flipped it 180.
I already mentioned the caliper bracket. It's an easy fix. Just cut off and weld on the other side.
