Not so plentiful here in uk.Yes, you may even find a real nice used one from Ebay. They are out there, just how much time do you have to find it.
Can I still use it until I get new parts.
Thanx but I am in the uk, so post and time ate against me. Towing it on holiday tonight hope to get if done when down at the coast, there are a few dealers there.End caps are cheap. Get a couple of new ones and fix it before it causes problems. If you tell us the drive serial number and the casting number on the rams we can give you the part number of the end cap. Also if it's internal lines or external.
