Project "It's a Jimmy Thing"

[JJH Jimmy]

After a year of working on this thing i am finally going to start a build thread! After looking for a blazer for 6 months i found this Jimmy in Colorado on craigs list. I went to pick it up and was impressed with the condition for what i paid. Just rust in the typical places like rockers, B-pillar area and the back of the bed on both sides. My avatar picture is when i just picked it up and was on my way home with it. The plan is to be a real nice driver with a 5.3 and 4l60e. Here is where i am at today with it. I fixed all of the rust last summer and have been working on the frame and engine all winter and blasted the body a couple of weeks ago. After i blasted it i dropped it off to my body guy for epoxy primer and to paint the dash and fire wall. I plan on putting raptor liner on the underside of the tub and anywhere there is going to be carpet on the top side this week end. The first picture is when i loaded it up to take it to blast (that sucked by the way). The second picture is when i dropped it off at the painter. The third picture is when i brought it back home and the last picture is where its going to end up.

yea, i know. I will post more pictures. I wasn't sure if any one would want to see more of the same old demolition and rust repair pictures.

Looks like it's actually pretty far along and you're back filling. Did you make the tank? It looks great.

...and it's not the same old thing, it's a Jimmy, Jimmys are better

Yes, i made the tank. It was a lot of work, but i think that it came out alright.

Here is some rust repair pictures.

Yes, it has definitely kept me busy the past year. Thanks!

Here are some pictures of the rust repair on the rear of the bed. After buying a chunk of some rear bed patch material it was obvious that the profile was not even close and the material was a quite a bit thinner i decided to form up my own pieces. It took forever and a lot of wasted material but in the end i am glad i went this route.

I searched for one closer but every one i went to look at was too far rusted for what i was willing to tackle. Plus, every one here in the rust belt wanted 3X what i thought they were worth! I got lucky. The guy i bought my Jimmy from was a real good dude and he described it accurately. He sent a ton of pictures. After i agreed to buy it i sent him a paypal deposit and he said he would hold onto it for as long as i needed him to until i could make arrangements to get it. About a week after i sent him the deposit my boss at work told me that we got a job in Colorado and wanted me to run it. Perfect! I elected to drive instead of flying. I ended up leaving to pick it up about 3 weeks from when i made the deposit on it. I spent a week getting the job going and then picked it up on my way back home, so bringing it home didn't cost me a dime! I guess me and this Jimmy were meant for each other.

Here are some pictures of the transfercase rebuild.

[JJH Jimmy]

I blasted and painted the front and rear axles. I also installed a 4" Tough Country EZ ride lift kit.

I mounted the transfer case with the advanced adapters NP205 to 4l60e kit. I was told by advanced adapters that they did not make a kit for the 10 spline NP205 and i had to piece it together from several different parts. I ended up having to cut about a half of an inch off of the coupling. After i got the output shaft in the transmission and measured about a thousand times i figured out that the output shaft was going to bottom out on the transfercase input shaft! I called advanced adapters and the guy i talked to this time wondered why i just didn't buy the kit?????? Really? Needless to say advanced adapters tech support really sucks and they are no help what so ever. The so called tech support people do not even know what they sell. Anyways, i used the chunk of the coupling that i cut off as a straight edge to cut an 1/8" off of the transmission output shaft. I am still a little nervous about the VSS signal wheel not being clamped to the shaft perfectly square. Oh well, i will see what happens!

Time to install the engine and build a crossmember! I didn't like the looks or the price of the Pacific Fab crossmember so i made my own. I mounted the engine and trans to the transfer case and blocked it up to obtain the correct pinion angle and started fabricating from there. I used 2" schedule 40 seamless pipe and mitered some 2" butt weld 90's to get the correct angle of the crossmember. I knocked down the welds and blasted and painted it. I made it so in case i ever needed to pull the oil pan i could do it with out removing the engine.

[JJH Jimmy]

I guess the next thing on the list is a fuel tank. So i made my own. I formed up some 14ga stainless steel and welded baffles and a fuel sump tray in it. Then of course pressure checked it!

[JJH Jimmy]

The top oil canned a bit when i welded the pump hanger and the level sender, but nobody will see it when the body goes back on.

[JJH Jimmy]

Next up is the exhaust and fuel lines. For the exhaust i used 2 1/2" stainless steel tubing and stainless Borla mufflers. I am also using the Trailblazer SS exhaust manifolds. For the fuel lines i ran them is 3/8" stainless tubing and used Swagelock compression fittings up to where i ran them up the back side of the engine then i used russell proclassic hose and fittings for the ease of routing.
