Picked up a really nice 51 Coronet Gyromatic w/ 230 Flathead. I’m 3rd owner, 10K original miles. Looking to put in a Gen 1 hemi and a vintage BW T-85 3 speed column shift.... more or less trying to make it a 50s correct Hot Rod. (Yes... doing up the Flathead is still in consideration ). Question is, will I have to replace the whole column or will the column for the Gyromatic be able to link right up? I’m thinking no as the column for the Gyromatic has R, 1(H&L) & 2(H&L)... and nothing for a 3rd gear. Yup... I’m THAT guy... so my apologies if someone has to explain or revisit AGAIN. Thanks for any help!!! Tips on 50s correctness are welcomed too! Again, thanks & happy upcoming New Year! hoop

I'm going a bit crazy, trying to identify a rattle noise that sounds like it's coming from the tranny. I have a stock P10 transmission mated to one of George Asche's OD units. Everything works fine, I can get to any of the gears, acceleration is good (for a 75 year old wagon), but it always sounds like there is something loose on acceleration or deceleration, and under normal driving loads. I've sorted through other possible causes; shifting mechanism, clutch, sheet metal attachment points, parking brake cable, and fluid level in the tranny and OD, with no change. Do these OD units sound like that normally? Am I worried for no reason?

So I picked up this Borg Warner R-10 overdrive from a buddy of mine up north, for the price of "on the house". He said it came out of a '52 Plymouth, and he showed me the flathead 6 that it was mated to as well. Not knowing much about these trannys, I said sure, I'll take it, and see if it could be installed in my B-4-B. I did some research on these, and I'm now informed they're known for being bullet proof and easy to operate. If I were to put it behind my truck's motor, I could get 5 speeds, keep my rear end as is, and make my daily driver more enjoyable and economical to drive. But take cover, the big elephant looms in the room.... Taking some preliminary measurements and observations: 1. The mounting holes on the bellhousing don't match up. 2. The throw out bearing collar surface looks like a smaller diameter (from memory). 3. Not sure if the input shaft is the right length. 4. The e-brake control is on the other side. 5. The Speedo cable needs to be longer. 6. And, finally, the driveshaft will need to be snipped a bit. Anybody ever do a mod like this in their truck? Not sure if I'm wanting to violate the backside of my flathead with a different transmission, I'd like to get some imput on the items listed above, and any others, from y'all. I like this option for OD better than a T-5 because I can keep the column shift, which I like. I had also looked into a Gear Vendors divorced mount unit, which would be easy to install and provide great performance, but they're cost prohibitive ($3k +).
