200 ultrabell

What bolts are yall using to put on a 200 metric ultrabell. They don't offer a kit for it nor do they come with it?

I took the stock metric oil pump retaining bolts length and added length to account for the thickness of the Ultra Bell. Found what I needed at a local Fastenal, specifying grade 8 bolts.

It is very important that the pump is on center with the crankshaft . The procedure is similar to dialing in a bellhousing on a stickshift setup . Just bolting up a JW bell using the existing pump bolts will cause the pump to have a lot of runout . Bolt up just the bell to a good engine block and tram in the pump bushing to the crankshaft , Dowel pin the pump body to the bellhousing , and you should be good to go .

FWIW M8x1.25x50mm is the size JW tech gave me when I contacted them.

Just finished one, M8 x 1.25 x 55 class 10.8 with hard flat washers. I bottom tapped the holes in the case to make sure there was enough thread depth.
Don't forget the o-rings.
