My 81 k20 has the 14 bolt semi with 4.10s. I always thought id but in a Full floater in it.
Just put a pinion seal on the semi and changed the oil. It looked excelent inside and has a posi. Lot of heavy use pulling a concrete pump for years and all that heavy hose in the back, seemed to hold up ok.
Whats a good price on a 14 bolt FF with 4.10s? If I dont find a deal else where besides a junk yard
Should I look for a particular year axle to go right in my 81 k20 ?

Not sure how much more a 14 bolt FF weights over a 14 bolt SF but it is considerably more, especially if running the 13 x 3.5 drums. The 14 bolt FF I used from my dad’s truck is open, no locker or limited slip.
Cost wise, around here 14 bolt FF range from $80 at a pick and pull yard where any axle is $80 regardless what axle it is (although they seldom have good stuff), up to $400 at other yards.
The best years to pirate an axle from is ’73-’87. The square body ’88-‘91 trucks with full floaters were 1 tons which the spring perches are wider than a ¾ ton so they are not a direct bolt in. Late model 14 bolt FF have a wider track width and just don’t look right in an older truck in my opinion plus they need perch work to bolt into an older truck as well.
