gday Ted,
nah, well, the sump didnt need any modification to fit into the 4k xmember, but the problem for us was the steering rack pinion is hitting the sump which makes the steering real stiff, and it sets off a vibration throughout the whole car... we are going to just knock the sump in a bit around the pinion, and that should be apples dude. :S
I also got it registered today and she pulls very nicely. took it for a long drive and got the hang of it, she's a beast.
i can't wait to get my lowered kings in, with some 15" volks it will look tough. i will keep you posted on the project.
