first thing you need to do is take that thing back. i did the exact same swap your wanting to do a 4cyl t5 onto a v8. if anyone tells you it can't be done or it's not safe bulldonkey. remember the 89 gt t5 was rated at only 265lbs and your std 4cy is 240lbs, it's a diff of only 25lbs. mines been holding up for the past 2 yrs and still going strong. if you got 3.73, you'll really love the tranny gears combined with it.
here's a reference link for the t5 info:

so this is probably what your looking for
this is how my pilot bearing looked like (btw bushing or bearing, tomatoes / tomato'es- it's all one in the same because the bushing you bought is actually inside your bearing)
here is a pic to verify it's all one in the same, i pulled out my bushing before pulling out the bearing... see pic

as you can see from my pic.. the actual bushing was all chewed up. so i ended up having to pull the whole bearing out.

easiest and quickest way to pull it out was to carefully drill it and tap it out, carefull not to drill into the crank
(learned the hardway)

go to autozone and pickup the "clutch pilot bearing" autozone part #14672. if you don't have an autozone cross reference it at the napa site or schucks for their equivalent. as you can see it is a bearing.

don't use another v8 bearing because the input shaft for a v8 is 16mm and the 4cy input shaft is only 14mm. this means there's 2mm for something to go wrong... be it vibrations or whatever. some may say you can get away with it. but 2mm is still alot when it comes to accuraccy. the part number is the exact size to fit into the v8 crank and slide over the 4cyl input shaft. there is not even a millimeter or play. it's a perfect fit. trial and error and several runs to the store was the only way i found out.... after getting everyone elses wrong info.
when reinstalling the bearing first pack the crank hole with tons of grease again. lube it up real good and also lube up the bearing good. then to prevent damaging the bearing grab a block of wood and gently use it to tap the bearing in flat and level. if you don't you risk binding up or tweeking the dang thing, and off to the store you go for another bearing.
here's mine installed... and YES i know my engine's dirty but it still runs 180+ no rebuild
