I have searched and am finding different answers. I got the billet oil drain from lil john motorsports. What thread Is the drain on the s480? I had read a bunch saying it was metric. I got the metric bolts and they don't work. I tried some from my bucket o bolts. Looks like my 3/8's bolts work. I didnt see anywhere though that said they were standard. What size is everyone using? Also the gasket I got from them is the standard size opening and the drain I got is for a 3/4 npt hole. I read alot of guys are just using copper rtv, which is the way I'm thinking of going. Wanted to see others opinion on here. Thanks!

IIRC my s475 used 15mm head bolts taken from some factory brackets on my Ly6.

from what I have seen the threads can be 2 different sizes. one standard and one metric. I dunno why. I always use a gasket cause I hate the mess rtv makes

I mist have ordered the wrong one. I only seen one on your website and that was the one I got. What is your part number for the gasket thats for the 3/4 npt flange? Do you know what threads it should be, too? Lol
