its actually pretty straight forward. i just put a tko 600 in my 2000 saleen. all you need is the bellhousing and either a steeda driveshaft spacer or custom driveshaft. you'll have to drill two holes on the mounting brackets for the crossmember. you don't even need the yoke the t-45 driveshaft yoke will work. and depending on the input shaft (10 or 26 spline) you'll need a new clutch disc if you have the 26 spline. you may need to remove or loosen headers if you have them. the t-45 bellhousing bolts are on the inside so it has to come out as one unit. that's the worst part. the install was easy.
