Default Anyone have measurement of side main cap stud?

I bought an LQ4 for a steal of a deal a few weeks back. It was all disassembled but everything is there. I literally have a bucket of bolts, fasteners, nuts, and studs. I have the long main studs picked out but cannot identify the side bolts. Does anyone have some laying around that they could take a picture and mic the length? If not, what is the gm part number of a new set of studs? I want to compare the price to ARP studs since my build is nothing crazy.

Thanks everyone

Try having a look under all the short 10ml bolt heads, there "should" be some sort of noticeable sealant..

hope this helps peace

I did some serious searching and found that it is a M8 X 1.25 X 24 bolt. I hope that helps someone.

Side Main Cap: 1.30in or ARP 1.28in
Timing gear thrust plate: 1.17in
Timing gear: 1.29in
Top head bolts: 2.12in
ALL other 10mm where: 1.51 - 1.52in
Except the 4 lifter tray bolts which has a lip under the head ..
