Realizing that ARP does not make a main stud kit for the 2.4L block (weird) I got crack-a-lackin on filling out there stud application chart. Spoke with Modern Performance and they said they always re-use the OEM main bolts. A few posts over @neons.org mention that guys run the ARP kit 141-5801 for the 2.0 however there is not 100% thread engagement by the nut. Their solution? Back the stud out a thread or two from the block.

OEM: 2.0 bedplate bolts:
M8 x 1.25 x 60
M11 x 1.50 x 65

OEM: 2.4 bedplate bolts:
M8 x 1.25 x 70
M11 x 1.50 x 75

After a couple phone conversations with Paul @ARP (very helpful guy) I ordered a set of studs/washers/nuts a la carte.

M8 stud: AF3.725-1B
M8 washer: 200-8641
M8 nut: 300-8340

M11 stud: ATP4.000-1LB
M11 washer: 200-8510
M11 nut: 300-8303

a quantity of 10 is needed of each.
w/o shipping cost: $204.72
