Rod cap bolts
 

Hey guys hope this is in the right place but I have to write it somewhere because I can't find something for my engine rebuilt.

I have a 300m 3518cc v6 EGG (yep it got the famous rod knock ,luckly I got it at start so I was able to even save the crankshaft ,1st cyl was the only with bad bearings) and the entire rebuild was going ok till I sent my parts for cleaning.The idiot there lost a rod cap nut (not the entire bolt).

Anyone has any idea what specs are those nuts?

I found some without specs in US for $1.16 per set....I live in Germany so it would be stupid to buy bolts from US.

Thank you guys in advance.This thing is really stressing me because everything was going so great.
