Where have you seen an AC subframe to fit a GasGas?

The AC subframe that works is the one for 95-97 KX250s.
It fits fine other than your you have to convert the seat mounting configuration slightly as the AC unit has the seat bolt threads cut into the subframe so you have to remove the threaded nuts that are "pushed" into the aluminum GasGas seat mounting brackets as the seat bolt has to reach through these to screw into the AC subframe.
The AC subframe is superior as there are 4 CNC machined "receivers" welded into the tubing as compared to the GasGas subframe that has the tubing "smashed together." These "receivers" are where the 4 bolts attach the subframe to the frame.
The AC's CNC recievers are less prone to bending or cracking. The tubing also is thicker on the AC subframe compared to the GasGas one.

Ouch that looks like that might have hurt!!!!
Even thought the AC subframe needs a little tweaking to get it to work it is by far a superior unit to the stock one for strength.
Personally I would recommend that the AC subframe be used to replace a broken/bent stock one everytime if you can live with changing the seat mounting brackets.

A little.
The rear hoop (fender support) is back ordered so I'm going to run with out it anyway. I'll have to see how long the fender lasts with out it.
If you run the factory tail light you might need it,, but if you run an aftermarket smaller taillight you will be fine,, My 97 has had no brace since I ditched the factory light.. same fender still,, 2 years of hard use and 3 of light use..
Oh,, I used the ufo dot taillight too.. the smaller led is lighter yet.. I think baja designs sells that? GF's might too..

Acerbis used to make a plastic rear fender brace, its still on my old '00 and worked great. You need something if your going to carry a plate, but that OEM loop sucks. My '03 had it and got tweaked several times. Maybe adapt one of the universal fender brace/plate holder/light assemblies, or make a brace from old fender plastic.

Does anyone know if that subframe fits all years gas gas? Having trouble with my seat bolt holes lining up with the seat mounting holes in the AC subframe. Both my new and old seat holes are about 5/8 to the rear of the subframe mounting holes. Trying this on a 05' 300. The subframe looks like the cats meow compared to my stock one but.......
