I guess I now don't understand.
The OEM part is the 1485, but you felt the 1480 was a better choice because it is stronger? If it does not fit without modification, is it really stronger?
I'm trying to determine, if while under the truck next week amidst EGR delete, up pipe, downpipe, hot side tube, front u joints, brakes and a tranny service; if I might go ahead and purchase spicer u-joints as well to replace the Moogs I had installed a few months ago on the rear shaft.
The moogs I got were 1480 series, but my squeak is still very present. The Ujoints installed without complication or difficulty, but in the effort to make my truck quiet if I wonder if I should get the OEM drop in 1485 from Spicer and call it a day.
