Oil return line bolts.

[chicagoboostin]

what size are the oil return line bolts?
(line to oil pan) (line to turbo)
i am guessing they are 8mm x 1.25 1/4 long...
i just want to make sure before i go to napa or ace to buy them.

not sure about length, but the head is 12 mm diameter if memory serves...if not, then 10 mm
