Re: FS: 63-72 LS swap motor mounts.

Yes you will have to trim the top flange of your frame to use these mounts. They will work with the '72 frame without trimming, because the '72's are narrower on the top flanges, since the '69-'72 trucks were available with big blocks. These are basically the '73-'87 mounts but with a different upper bracket to bolt up to the LSx engines.
