Lift-gate lock sbolt?

99 Cherokee has again lost the bolt that holds in the lock on the liftgate.
This is the second of the two original bolts. I remember that it was a weird, metric thread. Anyone happened to know the exact size? Was it something like 8.8 mm, 29 thread, metric. I don't recall the length. I would prefer not to have to remove the remaining bolt.

Thanks,

Ted

may try calling a dealer or auto parts store... can usually tell you price and sizes
