Default ARP flywheel bolts

I have a customer building two very high horsepower Subaru's (1000+ whp) looking for ARP flywheel bolts.

I do not have a bolt handy to measure for specs, I had the customer measure his bolt at M10x1.0 thread 28mm in length. It looks like ARP 254-2801 would be closest match at 25.4mm long or 251-2803 at 29.21mm long

Any of you guys ever use ARP flywheel bolts? If so what spec/part number?

If not, does anyone have a stock bolt kicking around they can measure the length of for me? Thread pitch is definitely right. I want to see if all 02-13 use the same length bolt.

Once I figure out a solution for this I will post up the information for future users.

---- UPDATE ----

I had a customer measure a bolt, supposedly measures 28mm. Pitch M10x1.0

It looks like ARP 254-2801 would be closest match at 25.4mm long or 151-2801 at 29.21mm long (but uses a washer)
