Thanks fella's! Was busy simply greening the underside and finally shot a pick. The one on the bottom is the original to my car. #600 WF
The one on top was installed by a prev owner. Haven't ground the snot out of it yet, couldn't get numbers off the normal place. Does appear that the tubes are plug welded on...Hmmm.
Thanx again
I'll start a post of the changeout once I start install.
