(I have a 8th gen Civic Si)Hey guys

, My stock inner transmission case took a **** on me (along with my clutch), There was a great deal on a rsx type s case so i bought it. The bracket below I purchased and installed (im using stock 8th gen shift linkage and shifter box) all gears work perfect except reverse. Does anyone here have experience with a setup similar to this? I wanted to buy the ktuned shift linkage since i thought they are adjustable(pretty sure they are but there around 350?). Should I just buy the inner and reinstall the gears back in to the my old set-up at this point(obviously a bit of work which im trying to avoid) and call it a wrap? Any help is very appreciated. Salud 🥃
