H Suhling Posted August 5, 2007 Report Posted August 5, 2007 A '49 Desoto came in to a local scrap yard and I am wondering if the rear end will fit in my B-3-B to make it a little more gas friendly. I would like to be able to just swap third members instead of the whole axle housing if possible. Thanks Harvey Quote
Phil Martin Posted August 5, 2007 Report Posted August 5, 2007 Harvey, be sure and check the amount of spines on the axles to be sure it will work. Quote
Guest jtw3749c Posted August 6, 2007 Report Posted August 6, 2007 The 49 De Soto rear ends were 3.93 or 4.10 gear ratio. Not much for gas savings. Quote
Guest flathead6 Posted August 6, 2007 Report Posted August 6, 2007 Check the hollender (sp?) interchange manuals but the thrid member from a mid fifty's chrysler six cly car fit into my rear end on my 1948 b-1-b. The third member fit. I took it a little further and swapped the cases so the 3:54 gears are in the b-1-b case. Helps get down the road.. I'd still like a t-5 OD. Steve Hanks Quote
Guest Dodge Joe Posted August 8, 2007 Report Posted August 8, 2007 Steve, The Hollender manuals can I get one that would cover my 60 Dodge truck? I noted they have diffrent years for that manual. Thanks Joe Quote
Young Ed Posted August 8, 2007 Report Posted August 8, 2007 You certainly can. However in looking through dads the truck coverage is very sketchy Quote
H Suhling Posted August 9, 2007 Author Report Posted August 9, 2007 Well rats, I was hoping the car would have been geared higher. But it don't sound like it is. Thanks for the info, Harvey Quote
Young Ed Posted August 9, 2007 Report Posted August 9, 2007 I would still take a look. What tranny does that desoto have? I think what you are looking for is a car with one of the versions of the semi auto. Also who knows whats been put in that car in the last 50 years. Quote
Jim Shepard Posted August 10, 2007 Report Posted August 10, 2007 I've heard that any late 40's to early 50's Chrysler with automatic transmission (or Fluid) will work. I think they had ratios of something like 3:56... I'm looking to do the same thing in my B2B. Quote
Tony_Urwin Posted August 10, 2007 Report Posted August 10, 2007 My '52 DeSoto wagon w/Tip-Toe tranny has the 3.9:1 ratio. Quote
H Suhling Posted August 10, 2007 Author Report Posted August 10, 2007 The Desoto has a three speed on the column Harvey Quote
Young Ed Posted August 10, 2007 Report Posted August 10, 2007 The only real way to know is to check. And of course they were nice enough to stamp it on the top of the casing where its the hardest to see. Quote
Rodger S-11 Posted August 10, 2007 Report Posted August 10, 2007 Hola Class Our 1947 M-6 type transmission De Soto "Custom" S-11 has an 3.5 rear axle ratio. Rodger & Gabby COS Quote

Yeah....ya can't always trust what's stamped on the rear end. I recently sold a 49 Dodge coupe that I installed a 3.55 ring and pinon in. The case is stamped 4.11. I told the new owner but he wasn't too interested so if he sells .....the gear change info will probably not be passed along. Quote
Young Ed Posted August 10, 2007 Report Posted August 10, 2007 Reg I have the same thing in my coupe. Case is 4.11 with a 3.73 gear set. I didn't want to send Harvey completely off the edge with that possibility. Quote
