What is it for ???

[bwbugay]

I have 2 of these sitting in my collection of car parts and Do not know what they are for.  Any help ???

total length about 5"   and about 1.5"  dia. spline

Looks like a part on the end of a driveshaft that goes in the back of a transmission.

i wonder about that......how would splines go though a seal

More likely it's the center sliding spline for a two-piece driveshaft with a center bearing. My 1962 Olds F85 has a similar center yoke. The center bearing is pressed over the female mating part that is built into the front part of the driveshaft.

Closest I could find but obviously not a match.

Could be a front axle yoke for 4 wheel drive ?

i was thinking that also 4x4......but any i have seen have a seal area........i also think maybe a split driveshaft ......and maybe the section it slides into has a nut collar that you slide onto this first......then stretch felt or rubber seal over........then slide the splines together .......and install nut with seal and tighten
