1937 oldsmobile L-37 !! Looking for rear end!! HELP
Hi!! I am struggling now to find parts ( rear end) for my car ! Has been in a - rear end shop here by fremont ca !!like 2 months! And they said , couldn't find the parts so now I am stuck ! Anybody knows ! If can a do a swap from an other car..?????
or where can I get help.!? Is the one in the right!!
If the rear does not need to be original... It should be pretty easy to make another rear - I am sure the wheel bolt pattern is 5 on 5, 1/2 x 20 wheel studs.
You just need the over all width drum to drum and we can suggest some rears that could work... Also we can totally build a NEW rear with what ever specs you want.
Just need the spring perch width center to center mounting hole, spring metal width to know what width perch to install (IE 2" 2.25" 2.5" etc)
What gear ratio do you want? Do you want positraction?
ANY rear can be used as this is a leaf spring set-up and you only need to get the width correct and then cut all the other stuff off the housing and install your perches with the correct center line and pinion angle.
Any 1937 thru '47 Olds (or Pontiac ) rear end center sections will bolt in to your '37 rear axle housing .
'48 thru 56 centers can also be made to fit by grinding the housing some so that the ring gear will slide in .
Hydra-Matic center sections offered much "higher " ratios (3.42 or 3.23 )that are much better for high speed cruseing than the original 4.37 gear .
I put a '54 Hydra-Matic rear center in a '37 Pontiac and it would easily cruise at 65 MPH.
L37 rear end.
Luis,
Did you ever get this resolved? If not, I have a stock 4:37 third member that I'm willing to sell. You would need to have it gone through just to be safe, but I pulled it from my running/driving 1937 Olds L37.

In 37 low rear ends were common place, engine only wound to 3 grand and no road was straight. You spent a lot of time in the lower gears pulling hills.... Tedd

Yes! I did know this, but still seems like a ratio found in a locomotive. I once drove my ‘40 to work 42 miles one way at 58 mph. I was both reluctant for the screaming and grateful for my lack of a tachometer, for ignorance is bliss. The stress made the back my shirt damp. No digression intended to the OP. Good luck with the sale. (Hard to find part)
I drive a miata nearly everyday with stock 4:30 gears. 80 is no problem of course it winds to 7 grand when asked....Tedd
You got overdrive. Allow me to introduce you to my van, it has 4.11 gears, no overdrive, and a Ford 302 sitting right next to your right knee that gets loud and proud at 60. Wisely, the gauge package didn't see the need for a tachometer as the engine simply tells you how fast it's going audibly.
You also have to realize the speed limits in 1937 were probably less than 50MPH so those gears were OK for traveling.
in 1937 I highly doubt speed limits were an issue at all...lol. ROADS on the other hand...were the issues... They just were not finished like they are now so high speeds just could not be sustained ....
1937 suspension I an sure was not top notch either as we have now...shocks, springs, tires, chassis mounting... etc not till 1956 did we really get the highways system really organized well ... with funding and safety quality... I guess roads in 1937 were much better than in 1903...but compared to today...Just not comparable...lol.
More useless info for you:
For the most part, speed regulations were widely ignored, and actually even abolished in 1930. Eventually though, a new act would be introduced in 1934 that set a 30 mph limit in areas that were 'built up,' but no speed limit existed on motorways until 1965, when a national speed limit of 70 mph was imposed
The first known speed limit established in this way was on U.S. 31 near State Road 28 in June 1937 at 40 mph.
