My searching has led nowhere. I'm trying to find stock shock length and travel for a 2g FWD and AWD. I'm hoping to use the info to get a Bilstein HD close enough to the stock length/travel to make it work. I'd measure it myself but I don't have any OEM shocks handy.
 
The FSM shows the stroke for any 2G front is 118 mm; rears are 154 mm for all models except the Spyder which is 169 mm stroke.

Using NAPA's part interchange system, the extended lengths show as:
Front - 39.39 cm
Rear - 53.39 cm

Would love to hear someone confirm those NAPA numbers though.

I called Bilstein's East Coast office this morning and so far found one promising shock for the rear. It is for a Porsche 914, #24-001793. It has a 13.25" compressed length and 21" extended length. Rebound is at 2,385 Newtons and compression is at 785 N. I didn't catch what speed those were measured at but if they are the same speed as the Eclipse these have much higher rebound than stock AWD shocks (1236 & 588).

The eyelet sleeve bore is 18mm instead of the 20mm on the DSM but a little machine work can fix that. I didn't get the eyelet sleeve length either.

I haven't looked for the front yet.
