From prior posts both here and on the DeTomaso Mail List...
NAPA part # BK(Belkamp) 819-5207 (replacement lift struts for a Dodge Omni)
Compressed length of 10.34", extended length of 16.77"
They work great according to a post on the mail list.
Larry Finch reports that he has them on his car and "the function is fine. Holds up my no-wing lid just fine, closes easily, doesn't seem to be too firm. Probably not strong enough for a winged lid. No information on strength (pounds) of force." Larry's on this board, so you can contact him directly for any additional questions.
Note: The NAPA catalog image shows this to have different fittings at each end, but this is incorrect. Both ends have the correct flat plate with a hole needed for our application. Total cost for two - $40.36
SACHS North America SG314005
Coz reported that these shocks will hold with or without a wing. "I took 4 pairs for some of the guys to Vegas this year and use them myself. And I was just corrected, they are $20.90 each."
I have not tried any of the above referenced parts myself as my car still wears its original decklid struts (which work only on warm days).
