These directions were made by Tmoss over at
www.allfordmustangs.com and these are the directions I used. I forgot you have to use your old TPS too. Mine did not require some of the mods he has though. The TB he used had no breather so he drilled it out...but mine had a breather, just pointing the opposite direction. My TPS went right on without any grinding of the tab also. I believe mine came off of a 96, so yours should be the same. Sidenote: My intake came off of a different 96, so it has internal EGR.
The mod took me no longer than an hour, so it's worth the time. Also, I spot welded my linkage on, I didn't want to use epoxy.
