I have 10 Skybolt SK2003-14 Cowl Mounts that I would like to sell. The Lord J7444-14 cowl mounts on my Cessna 150 need to be replaced so I ordered the Skybolt product which is supposed to be a direct replacement for the Lord mount. Turns out you also need the Skybolt fastener to go with the Skybolt mount. I don't have the fastener kit to go with the mounts and prefer to keep the mounts the same as they were. Links to the products are listed below.

Ed, mines a 1974 model 150. I replaced my mounts with the SKYBOLT SK2003 about 2 years ago. I didn't have to replace the fasteners,, just replaced the mounts. Are you sure you got the right ones in the first place? They do have 2 styles,,
