MG MGB GT V8 Factory Originals Technical - Driveshaft again

OK, I found a Spicer aluminum driveshaft to go from the GM T5 to the MGB rear end. How long does the driveshaft need to be, within an inch or two? I know Ill probably have to get this one shortened but I dont want to buy it if its too short to begin with. It is 44" longs and 2 3/4" diameter. Will this interfere with the e-brake?
Jake

Jake, out of couriosity, what is it out of? I would love to have an aluminium unit. Sorry i cant say what length the average unit needs to be right now.

The application is from '82-'84 camaro, but shop that has it say shorten and rebalance it if necessary. Ive been told to try and get the 2" or 2 1/2" driveshaft because they will fit, so thats why I need to know about 2 3/4". I cant imagine that it wont fit, its only another 1/8" more to the radius...

Jake,
If you have the driveline in the car, just get under there with a tape measure and measure from flange to flange. The shop should know how much play to allow for. i.e. If you need 36 1/8" while stationary, they may make the shaft so that the slip yolk (when fully compressed) is 33" and fully open is 39". Problem resolved.

p.s. I wouldn't trust the measurements of other cars for a driveshaft length unless you can 100% confirm you're using the EXACT same mounts, mounting locations, engine, trans, and rear end. There are too many variables otherwise.
Justin

Justin,
Thanks for the input, I'm not too worried about having it resized just yet, I just need to know if 44" will be long enough to work with. The engine is a '63 skylark, GM T5 tranny on factory 4 speed bellhousing and sitting in the factory position ie. not right against the firewall. I guess ill get under there today and measure approximately how long it needs to be and go from there.

Jake,

I can!

I used a stock diameter Camaro steel driveshaft. Every once in a while on a good bump I would hear a metallic "ping". I discovered that the driveshaft was kissing the parking brake mounting bolt that protrudes into the tunnel. I put a thinner nut on and sawed of the extra. It just did the trick. A larger diameter driveshaft and I would have had to remove the parking brake.

Something to think about.
