If your talking about the hubs, I would change to the manual locking hubs. I did it last night and it only took an hour to do both. I am planning on taking some pictures and posting in the next couple days.

The A/C, I was able to find some of the r12 so I had it checked out and that put in. Nice and cold. Definately helps here in AZ.

And my '88 has 3pt on the window seats also.
