Ok, I went to see a Blazer for sale for the 1st time. It had 31” tires. It had the overdrive. It was a 87 model and I took it for a drive. Man do all Blazers have that amount of power in them. Really a lot from what I felt. Well I took a look under the thing and checking with the pictures in the tech part of this side I think it has 10bolt axles, front and rear. So I guess I need a 12bolt for 35's? The only thing was, when I shifted past R through N to OD, the car jumped forward a bit. According to the owner this is probably wear in the driveshaft. Can that be true? I thought the rear differential would be a more logical choice. But he told me that it has been rebuild les then a year ago together with the transmission. He also said it had a 3.08 to 1 gear ratio. Is that ok for towing on 31”? Further, there were 2 radiators. One big one and one small one that was in front of the other and on the driver’s side. Is that for the transmission or could it be something else? Last things I noticed is that you were right about the space. Normally I need to put the seat as far back as it goes, but in the Blazer I had to move it a bit forward. Long time since I had to do that. Only thing bugging me was that it had no hitch. I don’t know if I can get those easily in this country. Biggest sting in the eye was that it is yellow. Not the beautiful bright or deep yellow, but flat, ugly. So this was my first impression on a K5 and my first ever drive in one. Tomorrow I’m going to the next one. I hope it has a better color.
