From the 1971 B&M catalog - I ran the TFVB-6264M, see the red arrows in the image. I also reverse engineered that VB and still have the fluid path info around. At the time I was also interested in the Clutch Flyte, and B&M indicated it was available.

I had a B&M Clutchflite with RMVB circa 1971 and it had no LBA.
