1991 Chevy Blazer (K5) Build

Here I’m attempting to track the process of the build on my 1991 Chevrolet Full Size Blazer (K5) **Last year they made the removable top.

Story starts: April 14th 2016

Just pulled in the driveway and parked the new Blazer. Had fun going through Memphis then down to Tupelo, MS to pick the K5 up then headed to Nashville for the day and night then home bound on Sunday. Sunday was a long drive in a truck I wasn’t familiar with but it ran good. Max speed was 80 comfortably and horsepower wise or that 700R4 would have to keep downshifting to please my demand for power.

So I didn’t realize how bad the interior was, its not so good. Dash pad is cracked, sliced and butchered. It appears they were trying to replace the speakers maybe since those are the only areas that are hacked. So new dash pad is required. Driver side seat back support is broke so you have a gangster lean to the right if you want to or not. So new seats are needed. Nothing else major except I want to change the wine color to all black which means a complete replacement of the interior which is going to be hell and expensive but look bad ass. Maybe even use billet for accents.

    Got it back from Motor City Steel.  On a 1-5 rating I’m giving them a 3.  Some annoying facts about the company.

    1. They never ever answer the phone
    2. They are slow..  they promise one time and deliver many many days or weeks after.

    Now why am I giving them a 3.  I believe they do good work.  Just be patient.  If you are in a rush stay away.  If they say a week count on a month.  If they say a month count on two months.  At least double whatever they quote you.  They are also a tad on the expensive side.

    So I got it back and it runs pretty good.  I would say I’m at about 75% happy with how it runs.  The trans is still a tad sloppy and it stalls every once in awhile when you first start it and finally, the torque converter locks up and you wish it would of waited just a tad longer.

    ***************

    On another note, I found out finally how to remove the top on the 91 K5 since its different then the rest because its the only year that comes with seat belts that come down from the top.

    Open the cover to the seatbelts there are 2 bolts that have to be removed. There’s also a plate behind the drivers side seat. Open that and there is a plug in there for the light. Then all that is left is the bolts on the top itself. It is a safety torx They sell the bit at auto zone. It is a size 40. We had to buy the bit because a regular torx will not do it. The bolts have a solid center to them. So get a bit that has the center taken out of it to accomidate the solid center of the bolt. Other than that have someone there to help you gently lift the top off and back. We slid it down to the tailgate and carried it off from there.

    Below is from a 75 but the cab and rails should be similar. The biggest difference is the seatbelts and electrical hookup for the light.

    Prepping for my drive to the Silver Lake Sand Dunes this weekend with some buddies.  I still have a trans leak (seems like its coming from the kick down cable but not positive). I checked the trans pan bolts and they are tightened to 12 ft lbs of torque like they should. Its currently got a cork gasket (which may get swapped for one of those nice FelPro gaskets) I just did my first oil change (put in 5w30 Royal Purple.. took 5qts) and used an AC Delco pf1218 oil filter. All joints I saw got some grease so ready to go.

    So fender issue is now much worse

    not sure what the solution is. I see a lot of articles talking about either

    A. Trimming fender (cutting the fender which takes away from the look but adds functionality)

    B. Moving axle forward by 1 inch (this could also help with vibration in 4wheel drive due to the angle but could cause issues with high steer)

    Wow, Kert at DIY4x responds pretty quick to online questions.  Seriously like less than 5minutes he also suggested moving the axle forward.  But how?

    A. Drilling the Spring Perches

    Pretty sure if I could move it just one inch forward I would be good but whats the best route?

    for my lack of confidence I lean towards the easy inch kit which is a plate under your springs that will offset your axle forward roughly an Inch
