i am currently looking at a 88 blazer. i am not a newbie to the 4x4 scene, but i am with a full size vehicle. my question is. everything i read bout a 88 is that it has IFS. is there any 88 that don't have IFS(like certain months that were built)? the blazer i looked at had leaf springs in the front. anything else that i need to look for when purchasing?
