I'm swapping the overdriven gearbox in my track-car for a dog-leg close ratio but just wanted to check if they are a straight swap with the same prop etc?

lol i guess we know who bought the dog leg then...how much for your 4spd over drive?

oh and I would think the drive shafts are the same...not much point in manufacturing a special box and drive shaft....not cost effective

Nope, the drive shafts have different length. And they can be connected to the diff and gearbox with either 3 or 4 bolts.
Check this topic: http://bmwe21.net/forum/viewtopic.php?f=26&t=9965

There are 2 lengths around for the doglegs, one requiring a different prop length, one that's just as long as the overdrive box. Check before you buy

good to know. must say im surprised.

Sold one example dogleg that was exactly the same length as my OD's last year that's why I know for sure...

No doubts! I know a lot about e21s but I dont know everything. one of the draw backs from only restoring them not modifying them. I havent had the oppertunity to get a hold of the really nice models that europe saw so alpinas and the euro sport models are totaly out of my knowledge base and I admit it. speaking of rare models (to me) is that e21 touring that is shown in the pics on the home page a real model or something somebody made very well?

Sadly, if you look closely the touring is nothing more than a bad photoshop. But did you know about the early touring prototypes? There should be one or two survivors of these cars, but ultimately BMW decided to go for a different design, the one we still love today! Anyway here's a link to only a little bit of info:

hmmm...not as keen on the prototype..somehow that look worked on the 2002 but not on the e21 in my opinion. still...would be nice to have a rare model like that. Maybe some day Ill win the lottery and Ill get the machine shop I dream of and make the touring. Ahh to dream
