Anyone ID this arm and body?>

So I got this old GSXR dragbike and want to know if the body work and swingarm are Kosman

[RONRACEME]

The swingarm definitely looks like a Kosman "double clubfoot" arm. The body work from the pic appears to be a custom mod of some sort. It is terribly unfamiliar, Air-tech maybe.

Does anyone make a DOT drag tire?

Not a slick, you wont find one.

Mickey Thompson, Shinko, Michelin, Metzler all make drag radials for 17" rims only. . .

The only tire that will give you any kind of traction on that particular rim, is a slick, being that its an 18" rim . . .

definitely a kosman arm.

Thanks guys. I talked to Sandy Kosman and he also confirmed it.
Heres a snag I ran into.
This arm was on a GSXR750. I plan on using it on an 1100 frame.
There are some subtle differences between the frame.
I actually had to spread the arm a couple of mm's to get the swing arm onto the frame. Apparently the 1100 has slightly more girth.
Second problem is the struts, I knew the on to the shock mount was going to be short since the 1100 uses a longer shock.
However the rears will have to modified too.

While talking to Sandy, he doesnt remember making an arm specifically for the 750, its possible he did, he just doesnt remember.
He sold a helluva lot of 1100 ones.

Anyways, do to the possible rarity of this arm, I am not sure I want to modify it at all. Sandy has expressed interest if I want to get rid of it.

Any opinions on this matter will be appreciated.
