Help I Lost my Distributor Bolt

[woodi]

So I recently got a 94 pickup that was overheating and dumping the coolant into the oil. Figured it was the timing cover being worn through from what I read. So I tore it all apart today and got it all put back together (One of the chain guides had broken but it didn't look like it had wore all the way through yet so I'm hoping I just didn't see the hole and this is gonna fix my problem). But anyways I got all done...well almost... and I realized I couldn't find my distributor bolt...I've searched everywhere and it's gone. So does anyone know what size/length it is so I can get another one? I really want to start this thing up and see if my problem is fixed.
