DimpleŽ EARLY FORD, GM AND CHRYSLER, ETC. TILL EARLY 1990'S
NEW 1/2"20X1/2" The 1/2"X20 oil drain plug was used historically all the way up to the late 80's and early 90's. Check your vehicle to be sure.......screw your drain plug into a 1/2"X20 nut and if it fits, that's what it is.
Now that the size is identified, it is time to screw in the latest and greatest drain plug ever made for this size, the 1/2"X20X1/2", Dimple® Super Magnetic Drain Plug.
We use a very strong 5/16" diameter magnet for optimum performance.
Do not delay in getting this great quality plug for your car.
