How to Make a Big Block K-frame

Did you look at the link? The '73-'76 SB V-8 K-frames are the ones to use to convert to a BB K-frame.

I missed that. I assumed that since the Schumacher mounts were for the '67-72 K-frames that so was the Big Block K-conversion.

The Direct Connection K-member IS a modified 73-76 small block k-member. Schumacher does have conversion mounts for this k-member, BUT they require cutting the driver side saddle shorter and drilling a new hole for the main bolt on the mount. It is usually cheapr and easier to make a DC k-member and use factory mounts.

OK. I was planning on swapping the K-frame out when I do the brake swap. Then I saw that The Schumacher mounts on their website only fit the 1967-72 K-frames. I wasn't sure what to do.
So I'll just pick up the entire front suspension including the K-frame, from a 1973-76 A-body and make the Big Block K.
