I fitted my ADM Ae86 front right inner gaurd tonight, and it sits in there quite nicely, complete with mud gaurds. (don't actually know if you need these, but had them off my other car)
All holes were in the right place as I expected with the Toyo, and front bar appears to sit in the mounting position without causing any clearance issues.
Did you have AE86 ones fitted or a retro fit from something else?
Mine is a zenki trueno with kouki front lights. Don't know if the gaurds are any different though.
If you want to fit them, I got no issues with it, just have to take them off again. I am not in a position to go to Regency for a while, so feel free, anything to get another trueno out there.
