Technical 1965 Lincoln 9" Rear

Anyone in the vast array of experts on the HAMB have any idea the axle spline number of a 1965 Lincoln 9" rear. I know if we guess it will be wrong. Thanks

 

I believe 28

 

Hollanders says it has 20 splines. Interesting.

 

65 should have dana axle.

 

Thanks to all, this one is definitely a Lincoln 9" and has Strange axles so it has been worked on. Open rear so I doubt anyone has changed the carrier. I guess we may have to pull an axle to count, that will take the whole team counting on fingers. Thanks

 

If it has after market axles, why are you even bothering to ask us to guess what they are? Just take it out and see what it is.

 

Strange, isn’t it?

 

Sorry to have annoyed anyone, we just thought we might be able to source the carrier needed before we took the car apart. Thanks

 

Lincoln’s some big fords, etc of that general era (maybe a little later) used a rear that looked like a 9” but was actually something like 9 3/8. Not sure what all interchanges.

I ran into this when, as a co-op student at Kelsey Hayes we pulled a big Ford rear from the Ford Axle plant to make a fixture for some brake development work on the brake dyno..

I was allowed to take the parts we didn’t need, which was pretty much everything but the ends of the housings. Ended up being a 9 3/8 with some ridiculous Highway gears. Dragged it around for years before I unloaded it on a friend.

 

31 should be the count. That maybe a 9-3/8 carrier but 9" will fit. Do remove axle and count..

 

Thanks to finn and seb fontana that was good info, I had completely forgotten about the 9 3/8 Ford rear from back in the day and I was there too. We will now definitely take it apart in that not only do we not know the axle spline but also the carrier size. Good also to know that the 9" if necessary will replace the 9 3/8 as we plan to add a Trac Loc along with some lower gears. This very traditional 31 has been around since the late 80s and has made multiple trips to Bonneville but that was in the past, now it will be staying closer to home. Thanks again.

 

You can ID the carrier by looking at the front of it, there's a curved rib on the 9-3/8

Any time you're working on a hot rod, you have to inspect, measure, and look up the parts to make sure you get the right ones. It could have anything in there....lessons learned the hard way, long ago.

 

Thanks Squirrel, that's another thing I didn't know or forgot. Seems to be a lot of that going on lately. I've been working on these cars since the 60s but never too old to learn something new.
