MG MGB GT V8 Factory Originals Technical - T5 Ford to MG REAR END DRIVESHAFT

I posted a question here a few years ago about a parts list for driveshaft parts to make up a shaft to connect the T5 to the stock MG rear end. I found the original question I posted in the archives, but the answer by "Jake" contained a link which used to contain the parts list I was looking for. It no longer works... Does anybody have a copy of that link or know what it is I'm looking for here? I would like to be able to walk into a driveshaft shop and give them a list of parts and an overall length and width and let them build me something. Any information here would be appreciated.

Thanks.

Scott, i used a 2" thicker than stock wall tube with the following parts:
slip yoke- Spicer # 3-5981X
End Stubs qty 2- Spicer # 2-98-1757 Just 1 if using the MGB dif.)
these use the 1330 type u-joint.
to bolt to the MGB flange, you need to reduce the dia. of the MGB end stub so it slips into the thicker shaft tube. this should be a temporary thing, with a healthy engine, the OEM diff. will probably not survive.

Scott, I have a driveshaft already made up that might just work for you. I pulled it when I added my Dana 44 rear-end. It was made by Front Range Driveline in Denver. It is complete but you would need the slip yoke that fits the T5, and U-joint installed. Please contact me off-line if you are curious..Chris PS: here's a picture

Scott, I used Jake's suggestions for my driveshaft and it works great. I actully saved his driveshaft page locally to my laptop. Here is the text from that page. Hope it helps.

"Getting a driveshaft is proving to be much easier that I though. I was able to find Spicer part numbers for compatible parts in the archives of the BBS, and was able to find an online Spicer parts catalog. With this info, I went to Six States Distributors in Orem, where they helped me figure out exactly what I need. They were also able to verify that the rear flange will fit the MGB rear end flange perfectly, and that it is not found on the Bronco II but is an aftermarket part. Here are the pieces required to make the driveshaft to go from a GM BW T5 to the stock MGB rear end.

- Slip yoke to fit the T5, Spicer P/N 2-3-6081X $50 or Camaro T5. I have been told that the T5 yoke and the TH350 yoke are the same.

- Rear flange to fit the MG rear end Spicer P/N 2-2-899 Same male pilot diameter, bolt circle diameter and hole diameter, as well as bolt pattern but with a larger U Joint. $40

- Front weld flange for 2.5" diameter tubing Spicer P/N 2-28-277 $16

- Rear weld flange for 2.5" diameter tubing Spicer P?N 2-28-1947 $17

- Front U Joint to adapt the slip yoke to the front weld flange Spicer P/N 5-3022X $25 if youre using the Camaro or GM yoke, Spicer S/N 5-153X if youre using the Spicer yoke $15

- Rear U Joint to adapt rear flange to weld flange Spicer P/N 5-443X $$15

- 2.5" diameter tubing, length will vary depending on engine mounting brackets used $.50 per foot of tubing

Any competent driveline shop can assemble and balance a driveshaft. Total cost estimated to be under $250, and this driveshaft will hold up to anything that the aluminum V8 can throw at it."

Thanks all for your replies. One more question...How do you know exactly how long to make the driveshaft? I assume you would measure the distance between the rear axle mounting flange and the end of the transmission with the car sitting on the ground or jackstands (engine, etc. installed) and then let the driveline shop worry about how long to make the shaft? Where does the slip yoke inside the T5 end up, in the middle of it's travel? Don't want to get a shaft that bottoms out in the tranny if I hit a big bump or leak because it comes too far out of the tranny. Stupid question maybe, but I have to ask.

Thanks again.

Scott,
I was advised by the shop that made my driveshaft to measure from end of the transmission, the seal actually, to the rear axle flange. They will know how long it should be with that dimension.
