1G throttle body compatibility

[DSM_One]

I am having the infamous idle surge problems with my car. I already have tried a few fixes like cleaned the t/b with a carb cleaner, replaced the o-ring of the BISS, and checked the ISC where I got around 38 ohms. After all that I'm still having the surge problem, I would next try thoroughly cleaning the t/b by dissassembling it and reassembling and check the throttle cables in the process but if ever I have to replace the t/b, would any 1G t/b work for a 1990 GS Turbo? And does anyone has a t/b to sell that would work with mine?

Thanks in advance.
