Unfortunately i didnt take any pics of the chassis leg, as when i was doing it, it was pouring down with snow and FREEZING!! I just wanted to get it done so didnt take the time to take any pics. Here is a pic of how it was done though. The black dashed lines are where the structure is now, the red is how it is originally
Its almost as if you cut the section out and inverted it. Strength shouldnt be compramised as ive actually got more horizontal strength there now then before, and its just in front of the strut turrets, so the only things its supporting is the front bumper, wings and lights. I angled the reinforcing piece i put in so it gives good vertical strength and should be the same impact resistance from the front.
Im not sure if you can bolt the Mondeo bell housing to the Jag box, although they are pretty much the same box internals, there are 2 issues i had with focus RS box and the mondeo box. The main issue is the bolt pattern is different. Look at the following pic.
Look at the right hand side of both the boxes. The mondeo box on the right is straight, but the focus box isnt. The top holes will mostly line up, but the bottom ones wont. Im not 100% certain on the V6 jag box, but i think the pattern might be the same as the focus rather then the mondeo, but youd have to check. The next thing thats easy enough to get over is the bearing on the focus box output shaft is a different angle, only by a few degrees, so to look at it you cant really tell, but when you try and put the bell housing on, it doesnt quite fit. If you arent very experienced with gearboxes it might catch you out.
I think the Jag transfer box is pretty much the same as the RS2000 transfer box, it certainly looks the same. Would be nice to have the Jag box too as its a 6 speed IIRC.
