Ok. I looked at all the blazers I could find. 6 in total. Unfortunately, 2 were S10 blazers. There was 1 ’87, 2 ‘88’s and a ’90. All 4 had an AC and the small radiator in front of the big one. All 4 also had OD (been told it is called a TH700R4). All also had 10bolt axles and to my disgust all had 3.08 gears. All were on 31’s and all had the same 2H-4H-N-4L pattern in the transfer case. So right now it is all about color and rust. Now one of the 88 ones had no rust, but there was some sort of leak in the cabin. Behind the drivers seat the floor was wet. What can this be? I found this very strange to find this in the best looking of all. The owner even showed me that the floor was wet but not rotten. He didn’t know there the leak was also. He was thinking that it was either the seals of the hardtop or a leak in the rail above the door. You know, that gutter. I looked there and there was a strange opening. Just as if the roof was not welded on properly. Can water make it’s way from there to the floor? Anyway. It’s going to be one of these blazer, so I think I’m looking for a 12bolt axle. Any tips or does anyone live close enough to maybe do some shipping? Just checking. XXX Lana. 6'5" tall Dutch girl about to upgrade her Jeep CJ7 to a full-size.
