just got a speedo cable for my 88 mustang lx 5.0 the old one was broken, looked like the line was twisted about half way up, and almost looked like it might have been snapped off at the gear. my problem is that the new cable i have the spring/wire that spins is sticking out about 2 inches from the end of the cable so im not able to put the gear on the new one. does it have to be cut down? wrong part? doing something wrong? and there was no speed sensor attched to the one i took off, i have one and it almost looks like it might work if i run it through that and then connect the gear to the end of the sensor
