Bolts for a T5 conversion

Hey guys in the process of a T5 conversion on my V6.

Can I use my Flex plate bolts on the Flywheel or do they need to be longer?

Also what bolts do I need for the pressure plate to flywheel?

Lastly what is the bolt size of the two bolts for the slave to the bell housing?

I have a donor car but the PO yanked the engine and got rid of all the goodies

Its always best to install new flywheel bolts dont reuse the old ones also when u get the new flywheel bolts make sure to get blue locktite dont want them backing them selves out also use new pressure plate bolts for the pressure plate locktite those as well

Can't use flex plate bolts for a flywheel. They're about a half-inch too short. Might not even go all the way through, let alone tighten up.

As said, just get new ones. They're CHEEEEEEEP. You can usually find em hanging on a card at yer local speed shop, in the Mr Gasket brand, along with many others. Prolly around $10 a set.

Clutch bolts are special. DO NOT use regular hardware, unless you have decided that you're tired of having feet and would like to get rid of them. Very cheeeeep also, about the same price as flywheel bolts.

Slave cyl bolts are 8mm by whatever the std thread is for that size. From the factory they have a weird head, something like 10mm drive w a washer head, instead of the usual 13mm drive for that size bolt. Mot sure if a regular bolt will fit, the head or a tool might hit the side of the cyl. If you can get Allen head ones at the hardware store, they'd work for sure though.

I disagree about the Loctite. I have NEVER in all my days, NOT ONCE, used that on ANY bolts on ANY car holding ANY thing on for ANY reason at ANY time. (granted, that's only a few hundred cars I've worked on, and acoupla hundred motors and transmissions and whatnot that I've built for other people, over 40 some-odd yrs or so of working on em, so I'm kinda inexperienced; but take it for what it's worth) Totally unnecessary when the job is done right.
