The crank holes or the clutch holes? Do you need the bolt circle dia of them, or the distance between the holes in each bolt circle? I have an LN2 flywheel (which is actually the same as the 2.0, 2.8, and 3.1, and can be used on a 3x00, so all those crank holes are the same). I can do it this weekend.

The crank holes. I need the bolt circle diameter. Its a 6 bolt so center to center straight across would be the same. Im trying to match it with an LS4 crank bolt pattern.

I couldn't find my spare flywheel. I know I have it somewhere. I just moved so it might not have gotten unpacked yet. I'll check again this weekend.

Good deal. No hurry. Just one of those funny ideas I have kicking around in my head from time to time.

this solves at least half your problem.

worth noting: the starter is mounted on the transmission.

if you want to use this with a manual transmission, where/how are you going to mount the starter?

Who needs a starter if you've got a manual? Just always make sure to park it on a hill.

Thats the torque converter bolt pattern. I need the crank bolt pattern as stated above. I spent at least 5 hours over two days searching here and Google. I'm sure if Google had my answer I would have found it.

There's a nice 3 page thread that I have running in Third Gen thats addresses most of the mechanical concerns for this swap. if you'd like to read through it.

I found it, but I didn't have a tape with me to measure it. I can get it out again this weekend.

Eco is ~69.45 mm, with a bore of ~39.29 mm, and outside diameter of ~282.58 mm

I unfortunately could not find my spare LD9 flexplate, if I do find it, I'll make sure to grab the measurements.

Youre killing me Nic! Haha. LS looks like its 78.75mm.

LN2/3x00/etc- bolt circle ~52.3mm, crank hole ~28.6mm

That's as close as I could get with my tape, I didn't have calipers with me.

Cool. Thanks a lot dude. I didnt figure we were going to get lucky with a factory J flywheel but at least the info is here now.

Just need an LD9 now.
