Funny you should ask....If you've been watching my posts on the E and D, I have a 91 S-10 I have been shredding today....It had a nice blue seat in it that measured up about right...My old seat stinks...and the stuffing is coming out making it like riding on pins.....I gave the blue S-10 seat a whirl and to my surprise, it slid right in. Not sure if I am going to keep it forever, but it will work until the stock one gets re-done....low on the list a this point....you will have to make a mount to hold the new seat in place..but it did not look like it was going to be a problem.
