New pickup with 3.4 swap clutch question

Hey yall,

I recently picked up this 1993 pickup with a 3.4 swap. I replaced the rear end. Now I am doing the clutch.The truck originally had a 3.0 in it and currently has the stock transmission and bell housing (slace cylinder on passenger side)

Do I run the clutch for a 3.0 or I have read that you should run the 3.4 flywheel and clutch but with a throw out bearing from a 3.0 clutch kit.

I just returned the 3.0 duralast clutch I bought for it . Called marlin crawler and they said to just run the 3.0 clutch kit and flywheel??

Thinking of getting this kit https://www.yotashop.com/toyota-5vz-swap-clutch-3-0l-to-3-4l-conversion-clutch-kit/. I have the flywheel bolts for the 3.4 also which are not the same for 3.0

Well either way I'm very excited about this truck and want to make sure I'm putting the right parts in it. Thanks in advance for any advice

3.4 clutch is a little bigger and will handle the power better. Honestly, a 3.0 clutch holds the 3.4 fine though. When doing a clutch job its best practice to buy a new flywheel anyway so that will take care of any of your compatibility problems right out the gate. If it was me I'd just go with the 3.4 clutch, and get a 3.0 bearing and call it a day. The fact you already have the 3.4 flywheel bolts helps with that justification too. You don't want to pull it all apart with a 3.0 parts in hand to find it has a 3.4 clutch and now you don't have the required bolts. Only downside to using the 3.4 clutch is cost. it cost a fair bit more than 3.0
