Trust me - I was not pleased when presented with a brand new drive shaft complete with new style centre bearing. He just sort of shrugged and said that's what it took - new from front to back only used the rear axle flange. I also had the bonded tube shaft not the M47 - and they didn't have the parts to make that work (some nonsense about tube size differences etc). The centre bearing can now handle a thrust load.
That's why I wasn't advocating doing this. The shop basically ripped me off and I was trying to caution the OP that all the singing about "it's cheap" and "don't worry about it it only cost me $150" might also end up like me with a drive shaft that cost almost as much as I paid for the car originally. There are online options (not really for Canadians - shipping plus crap exchange rate sort of kills that right now) and you could buy the adapter from Josh or just make sure your DL shop isn't going to bend you over...that is all.
That stinks.
I'm always a bit nervous about getting work done like this because sometimes I feel like both sides may not be 100% clear about what is the expected outcome. I definitely wouldn't have paid $700. I'd have walked away, but in my case I was only giving them a stock driveshaft and a center bearing, so not a lot of money invested up front.
In my case, I knew the shop i was going to had done similar work before, adapting a 740 2pc for T5, so I was fairly confident it would work out.
The other T5 swap I've done was for our lemons car. I tried to buy a stock 5.0 fox Mustang shaft from a yard that pulls the parts for the customer. It was available online, called, paid ($75), and went to pick it up a few days later. I walk in the office and there's an aluminum driveshaft sitting on the floor. Hmm, that's not going to work. It's gotta be at least 3.25", probably 3.5", no way it clears in a 240. Thought about buying it anyway to resell, but managed to stay focused on what I needed, and rejected this part since it wouldn't fit the 240. They had no other cars in stock that might have the right driveshaft, so they refunded my $75.
BUT...they have a row of shelves outside one of their buildings and it's lined with driveshafts. Some marked, some not. 1pc, 2pc, even 3pc. I borrowed a tape measure, measured the aluminum mustang shaft for length and flange bolt spacing, and headed out in search of a match. It took a little while, but I finally spotted one that looked right. Measured out to be correct. And on top of that, it was marked "86 Capri". That's a fox chassis...excellent. I got them to knock the price down to $50 since I had to hunt and find it myself, and I left a happy customer with the part I needed. It's been working great in the lemons car, paired with a prototype steel driveshaft adapter I got from josh for next to nothing because it wasn't even welded together yet. Cheapest T5 swap ever in that car.
By the way, the dampener needs to be cut off like so:
