Hello Ive recently tried to fit a tko 600 in my 98 cobra 4.6 4v. The shop got everything in and the pro 5.0 shifter seems very low almost like the trans is to low. We had to rolocate crossmember and were using factory mount.Also kt is using a drive shaft spacer whitch shop has installed at rear of drive shaft. Am I missing something here because something does not seem right. There are some things happening when moving in reverse and Im concerned something is wrong with install. or im missing a part or something. Ive stoped driving . Is there a special mount or crossmember? Also theres odd vibration standing still at about 2000 rpm coming from flywheel area. Im using a centerforce clutch and this was not there prior please help
