Distributor O-ring for a TO-35 with Z134 engine

[Checkptchickee]

Can someone tell me the size of the o-ring that goes on the delco distributor (clamp type) on a Z134 engine?

The Agcopartsbooks shows part number as 760001M2, but I can neither find a source nor information concerning this o-ring.

Thanks.

You should be able to take it to a auto parts and fit a O-Ring. Mark position of rotor before removing it to keep in time.

Thanks Miner for the reply, but I bought the distributor on ebay a while back and it did not have the o-ring on it.

I guess I could get the ID to the distributor and the OD to the block, but should the o=ring have any overlap to the distributor housing and/or block?

I've had mine out a few times and don't remember a over lap you should be fine

Thanks Trac. I will look at the setup more closely. Found another TO35 parts tractor this past weekend and am going to measure the o-ring on that one.

Thanks also to Miner for the help.
