Wow mach, incredible & exceptional detail, if thats 1 of the hidden details this mod is gonna have monster wow factor hehe , the scrolls look fantastic, I'd be scared stiff of dealing with acid thou and how to dispose it properly lol.
Bah, thought I found the bolts you were after, but checked your discription and I missed the essential brass detail, could only find stainless steel in your specification , I'll try a deeper search later but hopefully someone else might see this thread and be able to help. It's the fiddly hard to get bits that can hold a mod up.
I've been semi keeping away from here as I see some of the awesome mods progressing and wishing I could afford to start another myself lol, got a fair bit of spare sheet aluminium thou so I could at least practice and if I pull anything decent off I'll post it in the appropriate section .
