1980 sierra lq9 4l80e swap best hardware compatability questions

[Lq9'ed 80 Sierra]

I am planning on installing an lq9/4l80e in a static dropped 80 sierra 4x2. So far I have everything but the headers, ls swap mounts and oil pan(truck is very low). I plan on using my existing low mount ac compressor with custom made lines so they clear the frame(cheaper than spending $$$ for a high mount bracket). I will be using a floor mount American shifter dual action 23" so shift linkage is not a concern. I need to know what headers and ls mounts work together without frame or a/c comp bracket or engine mount modifications. I have spent countless hours searching and cant seem to find any answers. Does anyone know what long tube headers and swap mounts work without having to cut up the frame ? I am open to other options as well, such as mid tubes instead of Lt's. Id also like to keep my driveshaft. Right now I have a 200/4r drive shaft but have a drive shaft for a 700/r4/th350 truck.
