Does anyone have a 1988 Iroc w/FE2 suspension with the original yellow Bilstein shock absorbers? The originals will have a label showing "Bilstein" and "Delco". There should be an 8-digit P/N stamped at the very bottom of the gas tube (not on the mounting bracket). There is also a date code 180 deg around from the P/N. You have to wipe off the road grime in order to see them. If you have this info, please reply. Thanks.
