Anyone seen such a thing, specifically for the 70's? The rear shocks on my 72 have begun to leak - finally! Supposedly they're OE Porsche RSR shocks, green Bilstein with part number 911.333.051.35AE. The Bilstein part number (?) is 000012088. Also, the lower mount is stamped with the numbers 170 and 180.

Of course, I need to replace these. But with what? Grady in a pinch to use 911 Bilstein race shocks. It would be nice to find out what the specs were/are.

Thanks
