Stock 305 clutch size?

Does anyone know what the stock clutch size is for a 305? I can't find it in my manual, and I've noticed that there are 10.0", 10.5" and 11" versions available. I THINK it's 10.5" but I'd like to verify that....

Thanks!

My '83 Z W/LG4 had a 10.4" disc and a 153 tooth flywheel.

Just to be safe, you could do like I did and buy clutch kits for
the 10.4" and 11" and return the kit you don't use. It is
possible that your H.O. might take the 11" unit.

It's 10.4", often called 10½"... no improvement in the HO cars unfortunately

McLeod makes an 11" version that works great. The others are 10.5"...

Hmm- sounds like I'd be better off waiting to pull the engine first... but chances are I've got the 10.5", right?

I did wonder if the HO option would've given me a larger clutch- guess not....
