CPP Brake Calipers (4035 and 4036) for 73-87 disc brake swap? Brake hoses?

[RoyL]

I bought these calipers from Summit CLP-4035B and CLP-4036B. Discovered the 73-87 brake hose won’t fit. Calipers have 7/16x20 threads and banjo bolt. CPP tech answered hose fitment question on Summit as below:
“The 1971-1978 hoses will work, that's when they used disc brakes. Our part numbers BHK-R7 (1/4 inch hard lines with 7/16x24 threads) or BHK-R7-68 (3/16 hard lines with 3/8x24 threads) will work.”

I believe my hard lines are 3/16” so won’t fit their 1/4” side…
Anybody run into this? Says they are only 16” long, may not be enough?
If I were to redo my hard line, then their hose may work…
Thx
