I purchased a main shaft nut from Cobra Transmission recently. It did not fit. I have been arguing with the guy about it (trying to get a $9.00 refund). They are asking for a picture of the nut that does fit. I ended up reusing the original nut and its inside the sealed up transmission. If anyone has one of the factory nuts laying around and would not mind taking a picture using calipers to measure the width inside the threads, I would greatly appreciate it. Here is the picture of the wrong main shaft nut (the threads are too big).
