I ran mac lt with the stock t-5. Had to dimple the mac and grind a little off the clutch fork area... this is a 10 year old memory, so I don't remember anything other mods... running bbk lt and tremec now. Hope this helps.
all TKO setups = fox bell housing which allows the use of fox headers.
The driver side will not let the bell go in. Itd take a huge dimple plus a lot of grinding to get it to work. Maybe I'll try grinding and see how much room I can find. But as of now the clutch fork being at a different position than foxs make them not fit.
I'm running 94-95 MAC's with a fox bell, extended clutch fork, and TKO transmission. I had to grind a decent amount off the bell where the clutch cable goes through it as it hit the header. The header now touches the bell there but it fits.
