This is original shackle set up on my 59', the pins and bushings came from LMC. I used a threaded rod and 2 sockets to press out the old bushings and install the new ones, worked very well.
Interesting. I'll look at their site again and see if they have the pins and bushings. They probably do and I missed seeing them vs the complete kit. All I needed was the pins and bushings of course. Also thanks for the rod and socket idea! I had tried a socket but realized I didn't have enough room to get a solid blow (or several) with a hammer. I've already taken off the side step and had to cut that hardwear, and lifted a plank from the bed to move a wrench, and the handbrake cable. I'm not wanting to remove anything more just to swap springs.
