Delco Part Numbers Explained
Almost all Delco lever shock absorbers have, somewhere on the casting, inscription "Delco, Made In Dayton, U.S.A" (on some word "Delco" is replaced with "Delco-Lovejoy" or "Lovejoy").
Part number is a four-digit number with a letter or two (e.g. 1948A, 1430CA, ...); letter portion is used to distinguish between left and right or between shocks with identical bodies and different arms. The part number can be found on most shocks:

- on shocks with screw-on caps on each end of the body, on one of the endcaps, usually on the cap on the arm side of the body;
- on shocks with cover plate (held on the body with ordinary screws), the number is usually on the plate;
- some shocks have number stamped on the valve cover (looks like large, approx. 1/2 inch diameter screw or nut)
