In 2012 I inherited a '58 Del Ray project car from my Grandpa before he passed away. From what I know about the car...he bought is without a front end...pieced it together from other donor cars...and put in a rebuilt 350 engine and used TH350 trans. I assume used tranny because last August I finally replaced the entire fuel system (tank, electric fuel pump conversion, lines etc.)and got the car driving, yet right before Thanksgiving I lost drive completely. Reverse works, but drive and low won't engage.

Now I think my Gramps knew the tranny had issues, because he hand a complete rebuilt TH350 in the trunk with new converter. So 2 weeks ago I research and prep myself to get this tranny swap done. Unfortunately to my surprise, I find out after I installed the rebuilt tranny, I am 3" short and can't install the drive shaft. That's when I learned the old tranny had a 9" tailshaft and the new one has a 6" one.

After must research I am thinking I have 3 options. Get a 3" longer yoke for $35, Get the driveshaft lengthened for $180, or get the tailshafts swapped which would run me $275.

I leave my decision up to the experts here, as I am a complete novice to old cars, though I do have decent mechanical and aviation skills.

Welcome to CT.

Not sure if this can be done but,
Could you not take the 9" tail from the old and swap it onto the rebuilt TH350?

The TH350's came with 3 tailshaft options.

Go with the longer front-half of the driveshaft. Much less work than converting the transmission to the longer output shaft and tail-housing, and a longer yoke opens up potential vibration and other issues.

Get a stock front driveshaft for any year X-frame car with any trans. It will be longer than you need. I mean a used shaft, not a new one.

Have a driveshaft shop shorten it to the correct length for the trans you want to run. This means one cut and one weld, which should cost about $50 unless the shop has a minimum 1 hr charge. The shop will probably try to talk you into paying for a balance job. I leave that decision up to you, but I have never found it to be necessary as long as the shop does not remove any weights which were already on the shaft.

If the shaft you get has a 16 spline yoke, swap the 27 spline yoke from your present shaft. Both yokes take the same U-joint, so just use whichever U-joint looks or feels better.

It can be done, but it requires completely disassembling both transmissions to do so. Which was my $275 option

Do what Ray said, find a used front shaft, 58-64, any motor or transmission. Easy to find and should be cheap. Correct length to shorten it to is shown here in a sticky at the top of the forum.
Make sure the yokes are "clocked" the original way.

If I replaced the 4.5" yoke with a 7.5" one to make up the 3" difference, would that work as a temporary fix? I only ask because money is tight right now and I found one for $40. I can't keep this car raised 2 feet in the air in my garage, as most the jacks and stands are borrowed parts and I would like to drive this car to re-position it in my garage as well.

front half?....My drive shaft is a one piece shaft. I hear this car came with a two piece, however I think my Gramps had the shaft swapped to a one-piece to make the 350 engine and TH350 configuration work.

When I got my Delray, it had a 350/350 with original 2 piece driveshaft and ran just fine.

Maybe try to locate a complete original to use.

It may have been 2 piece, but it most likely was not original. The only stock X-frame front shafts which are the correct length for a 6" TH350 came on cars with a 4 speed or a 3 speed + OD trans. These are quite scarce and fetch accordingly high prices if the seller knows what he is selling.

Most builders doing a trans swap will either shorten a stock PG or 3 speed (no OD) shaft or else have a new shaft made if they want to spend the money for it.

I forgot to include the following note in my earlier post.

In case you are not already aware, 58 driveshafts are shorter than 59-64. This is because the 58 has a shorter WB. Even if you can find and are willing to pay the price for a 59-64 4 speed or OD shaft, you will still have to shorten it anyway. In other words, there is no point in paying a premium price for one of those shafts because it won't gain you anything.

ThanX Ray,
I will have to check the length of the shaft, it currently resides on the floor under my car as I swapped in a 700R4.

I will check it against a second one that was in the trunk, I suppose one is the original and the other from one you mention.
That or the previous owner had the front shaft cut down.

My current yoke measure 4.5" from center of U-joint to front of spline shaft. I found a 7.5" yoke for $40. Wouldn't that work to make up the 3" difference?

No one seems to answer this, and looking online I am not finding any used 2-piece shafts so that fix is a dead end.

I found this one on ebay and also an OD/4 speed shaft for $250 which you would still have to shorten. The $100 shaft is more money than I was expecting, but I guess these things are getting scarce. You might want to grab it before it gets away.

Both of those are very rusted out. Don't think I want to invest in that when my current one is rust-free. I am going with the longer yoke and will keep you all informed on how it works out.
