Once the rear brakes were done I finally got to mount the Blazer tank and skid plate.  I will probably build a beefy pintle plate on the back for some added rear protection and towing convenience.

I finally got the 700r4 out of the Blazer and it was a total sh*t show.  On the passenger side the bolt below the dowel pin broke and the one above it needed to have the head ground off.  I essentially had 3 stuck dowel pins on that side, and the bellhousing suffered a stress crack on one of the ears.  I have convinced myself that a 700r4 is the tranny I would like to go with for the overdrive and no computer.  Also read somewhere that the "K" case is the one to have.  Unfortunately I cannot weld forged aluminum with what I have, so I will bring it somewhere to get fixed.

Whats wrong with this picture?

LOL the bolt sheared on both sides and the head and nut are still rusted to the shackle.  Figured this would give the truck a bit of a lean to the passenger side.  Nope!the drivers side bolt is also sheared on both ends.  I don't remember taking any jumps in this thing.. maybe the 500 extra pounds hanging off the front for 15 years had something to do with it?

I know its been a while, but I wanted to update this build.  Ive been putting an addition on the house and haven't had much spare time to get out to the garage.  Since my last entry I have done a bunch of little stuff and got the driveline installed.  The motor came from pace performance and the trans and TC are the ones from the K5.  The motor package came with a Fitech EFI system that should (hopefully) work well with my in tank fuel pump.

I am now in the process of running some fuel lines from front to back.  Got some lengths of "vapor guard" hose, a filter, and a pile of fittings.  Ill also probably add pressure gauge somewhere convenient.  The feed is 3/8 rated at 225 PSI.  The hose for the return (5/16 vapor guard) is rated at 50 PSI and has printed on it "not for use with EFI", despite the fact that summit has it listed at 225 on their site.  I am assuming that this hose is not intended to be used on the feed side of an EFI system but is OK to use for a return line.  Correct me if I'm wrong but my understanding is that the return line should get only residual pressure from the regulator in the throttle body, which is less than 10 PSI.  Any thoughts or tips for plumbing the fuel lines would be appreciated.

I am sure that I will eventually regret going with the outdated hydraulic plow setup, but I wanted keep the old school vibe on this build.  Cleaned up the plow frame and installed it so I could run the brake lines around the huge bolts that hold it on.  During one of my craigslist browsing sessions I found truck for sale with an old plowmate on it.  After some discussion I managed to convince him to sell it for $50.  What is a plowmate you ask?  Well, its a heavy duty brushguard that replaces the unsightly plow headgear for some off-winter style.  I dont think that Fisher sold many of these back in the day.

Before I paint the front driveshaft I noticed that this slip yoke seal is wasted.  Looks like changing it involves removing the cap and swapping out the rubber seal.  I have two questions:

1 - Anyone have a source / part # for that seal?
2 - Getting the cap off looks like it involves a torch.  Will it come off without mangling it?  Are replacements available?

I ended up going with these double line clamps for running the fuel lines.  They are 5/8 X 5/8, so the feed line fit right but the return line was a bit loose as expected.  I ended up wrapping the return with some electric tape to thicken it up at the clamps to make it work.  Used six of these attached to the frame at about 18" spaced apart.  There are two closer together under the rear cab crossmember to support the fuel filter.

The rest of the way will be attached to a bracket on the back of the engine that I will invent later.

Got help from homeboy Stig to get the cab on for some mock up.  It is starting to get cold here so I wanted to get thing ready to work on inside for a while.

I put together all the parking brake cable parts and realized that the rear cables were too short.   Was hoping all the stock stuff would work but the eldorado calipers in the back needed something longer to reach.  Took some measurements and started searching the inter-web.  Found that these cables (made for 67-72 1/2 ton with 127" wheelbase - 48" cable / 34.5" housing) fit perfect.  I cut the cable spring off on the back section since the caliper had a built-in return spring with more than enough tension.  Installed the pedal in the cab and got it all adjusted to work.  Chances are ill hardly ever use it, but it needs to be there for a sticker.
