Measure the lenth of both rear ends. see iss all hardware will bolt up without fabrication. if its the same size it will work. But im afraid being a 4 wheel drive it will be geared lower then a regular pick up/ Drive shaft may work but if not it would have to be shortened or lenghthebed. alot of work. Brakes you could leave the non drum breaks on better stopping power. I honestly believe you would be better off just going to a scrap yard and find one very easy to remove and replave few hour job.

Get a Haynes or Chiltons Manual for diagrams and instructions for your vehicle.

If your talking about the Check engine light. You will need a CHEVROLET OBD I code reader. the auto makers used their own style of ports and language until OBD II in 1996. The code reader can be purchased at most auto parts stores and it isn't very expensive.

yes it will bolt right in.

It's not worth doing all that conversion, buy the time you spend the time and money to convert the 89 4.3 to work on the 98 blazer, it would be cheaper to install a 98 vortec rebuild. The 89 4.3 have a TBI fuel injection system and the ecm on the 98 will not work and the bad news is that the ecm on the 98 also controls the transmission shift points and the 89 will not, so even if you swap the ecm to have the 89 4.3 engine work. the transmission will not shift. Sorry for the bad news but it would be cheaper to replace the 98 engine with the years of 1996 to 2001. Good luck and hope this helps.
