What info do you need on the intermediate shaft? I have both shafts out of a 2000 1200 SUV I parted last year that I can measure up for you.
Edit: I guess all I have left is the shaft, I shipped the entire midshaft assembly with the engine. it was 205mm in length but it had a few steps and shoulders in it that would need to be machined off.
Here's a link with more info on intermediate and drive shafts;

What kind of Impeller selection are you going to find for the 14/19's? I had a Skat Swirl 14/19 but was told it was way too tall for a stand ups and was too far away to be repitched to anything useful.
