Apols for the late reply - been away for a bit for work, had to go and pass an ultrasonics ndt course - woohoo, show me the way to pay day! Anyway...

The diff case measurements are just as I took them from the chassis, I didnt actually check to see what they came out at tbh. Or have I snapped onto the wrong point when drawing them in...?
Im guessing u are ok now with u having a diff to work from - or would u still like a revised drawing? its not a problem if u do. unsure if the rear is exactly the same hole spacing as the front, due to my chassis being half built up at the mo! Lol, I can pull it apart and check if u like tho?

That front bend is 30 degrees on my JT chassis iirc, I think I added that as a note on the email with the drawing attached. My stock cen one is slightly under 30 degrees - I put that down to wear and tear. Its a single point bend with the bend fulcrum point shown, I think, on the drawing I sent. I have the version here that I mean, if I sent a different one - would u like it sending?
I drew the bend as it is, rather than as a true contruction drawing, apols for any confusion there. Worth bearing in mind re the inner radius tho, for the diff casings, a sharp corner there on the cases wont let them fit properly.
