The final truth?...
Before all you tripode-boys all go out and buy LSDs thinking all you need are some circlip pliers, I've done a bit of finding out meself...
Cosworth - did you try all this with a lobro type diff or an actual LSD? Cos I think there is a significant difference...
From what I can tell the ends of the shafts that actually fit into the diff are the same length (left and right) on the tripode shafts. This is also
true for non-LSD lobro shafts, so you can wip out the flanges from a lobro-type diff (being identical left and right) and use your tripode shafts, as
Cosworth has found.
If I'm wrong about this and your tripode diff inputs are different lengths then I'll shut up now (and I know the actual shafts
themselves are different lengths - I'm talking about the part that fits into the diff). I dont actually have any tripode shafts - but I have a
sierra V6 haynes manual with nice technical drawings of the innards of both types of diff.
HOWEVER...the insides of a genuine LSD are different to a non LSD (even one with Lobro shafts). With the LSD plates sitting on the left hand
(passenger) side, the diff mechanism is shifted over to the right hand (driver's) side. Consequently the lobro quarter-shafts for an LSD are
different lengths left and right. So tripode shafts wont fit in properly!
I found all this out in the last few days of driveshaft reconditioning and diff fiddling. Here's a photo if the inner ends of my shafts.
Coincidentally (or not) with an LSD your 'short' shaft is the same length overall as your 'long' shaft! Looks like there's
no easy LSD option for all you drum brake/tripode geezers

this was tried and tested and discussed at great length on the interford.co.uk bb - a man called Dojj had the ultemate answer that lsd shafts are for
lsd diffs only and shafts that uses disks can be used with the lsd. however, normal drum brake shafts cannot be used in an lsd diff or disk brake diff
setup.

I have physically tried the following-tripode type shaft onto LSD type diff as I remember it worked OK both sides-I will check again tomorrow-lobro
type shaft into LHS of open type diff only will try both sides tomorrow and give definitive answer

This is the final answer. The long quarter shaft from a lobro joint driveshaft will fit both sides of an open type diff. Tripode driveshafts will
only fit on one side of an LSD diff-sorry for the bum information earlier.

Just tried to fit lobro quarter shafts to an open diff-they definitley work as well so you can fit either lobro or tripode type shafts to either an
open or viscous LSD type diff
BTW (I guess Cossie will be able to answer this), which models have LSD diffs? And are these 7 or 7 1/2 in? Are they all disc-braked?
Thanks for helping. Cheers

One idea?
Taking my idea to its end, can you use the inside parts of a lsd driveshaft and retain the outer ends non lsd "drum brake" by getting them
cut and welded as i know that the type i have, the driveshafts are compressed when assembled, could this cause a problem, are the lsd types
compressed, also does anybody remember how much it costs to have driveshafts made up balanced etc
