R380 gearbox: Help needed identifying
Hi all, just looking for some help identifying an R380 gearbox, it is a 2WD box (short input shaft out front and remote mount on rear) and has a 73A prefix (L suffix).
Does anyone know what car (or van) this would have originally been used on?
Is there an identification table published anywhere on Internet, I've searched but maybe not being imaginative enough on my search terms, I've seen some identifications but no 73A, although I have seen confirmation that this is a legitimate ID.
Out of interest can anybody tell me what vehicles the 2WD 'box was used for? Obviously Sherpa but what about Morgan/TVR/MG? Any other possibilities?
Thanks in advance

That's not going to be happening I'm afraid.unstable load wrote:If you don't want it, stick it in a box and post it off to me for proper disposal.
The best I can tell is the 2WD variant of the R380 was used in some TVRs, Morgans as well as Sherpa vans and black cabs.
I'm hoping mine is from one of the first two, particularly as the Sherpa box had lower 1st and wider ratios to make up for that.
I'm replacing an LT77 and have a few modifications to make, as my car is already built I'm going to have to shorten the remote (or make some other changes) and I'm hoping the rear of the box doesn't foul my chassis or there's going to be some 'surgery' involved.
If anybody has done a similar mod', did you notice that the remote input shaft has the cross hole (which the remote picks up on) at an angle when in the mid, 3-4 gear, position?

Can you pop it into first and count the input/output turns ratio to determine which box you have?
In fact it doesn't really matter where your box was from as long as the ratio's work for your application - so I would just count them, and using your rear diff ratio and tyre sizes you can work out your various speeds vs revs.
