Is what a WAAG ???
Are you talking about that old Russian Jeep? The Data Plate on it (for what 'Russian' I can read) says it is a 1974 WAZ. Fun little rig. Little 4-door / gas 4-banger / 4-speed with the standard old 'JEEP' style tranny & xfer case shift pattern. Full floating axles. Tough as nails. Ran like a Champ, but was a bitch to get filters for. Had to do a little 'creative' plumbing to get a K&N kit on it.
FUN as hell :-)

What is the 'repair' that your are doing with the A/C Elbow? What is wrong that needs fixing?
