I am installing new body mounts on my 71 blazer. I have done the radiator mount now I am on to the first one and I can not find how to get to the head it doesnt come through the floor of the drivers side like all the other one down the line any ideas on how to get the bolt out? Do i have to pull the fender to get to it i can not see where it comes out at. All the computer anybody has only go to 1973 and it says the bolt goes from the bottom up but 1971 does not.
