which rear end '74 3/4 CC

Does anyone know what rear axle came on a 1974 Chevy 3/4, 2wd crew cab with 3.73 gears? Would it be a 14 bolt FF? Thanks in advance!

GM CORPORATE 14-BOLT
The "small" GM 14-bolt has a 9 1/2-inch ring gear diameter. It was used in the rear of 1964-and-later GM pickups, and in the rear of 1984-91 3/4-ton Suburbans.

Should be a FF 14 bolt with a 10.5" ring gear; NOT to be confused with the 14 bolt SF with a 9.5" ring gear that was used in 80's 3/4 tons. The 70's 3/4 tons and all one tons used the axle you probably have.
