Thanks for the kind words, Jaap.
Did some woodworking this weekend on the rear body. This type body uses tongue-and-groove lumber for the front panel, floor and tailgate, and maybe some in the lower lockers also.
Haven't worked with wood much, but was able to make the lumber after a few failed attempts. Still have to bolt it all to the front panel....
Had a setback in that the Chevrolet Blazer rear axle I installed will be too wide once the rear fenders are put in their correct place. The problem didn't become noticeable until the rear body was on...
Think I have found a suitable, cost effective replacement for it, though.
Thanks, David

Hi David

Your problem of the axle housing being to wide raises and interesting issue for any of us who discover that we must come up with an new axle housing or differential unit if a CMP replacement is not available.

Over the years I have broken both rear axle shafts on my HUP. The first one I was able to replace through the kind help of another MLUer who found one and shipped it down from Canada. When I broke the second one, no replacement was readily available so I went the route of a Hot Rod machine shop that builds/produces axle shafts fore race cars. Result was a CMP axle rated up to 400 hp.

Which leads me to my point have you taken a look at having the Blazer housing narrowed to the correct width and then having the axle shafts shorted or new ones made?

I'll dig out the name of the company that machined up my axle shaft think they are in Colorado. Found the link to the company http://www.markwilliams.com/

Also it goes almost without saying the pictures of project are showing really good work.

Default rear axle...

Hi Phil,
Thanks for the link!
Thought about having the Blazer housing and axles narrowed, but is very expensive from what I've been told.
After some research, I came up with a solution I think:
Isuzu pickups came stock with a 5.5" on six lug bolt pattern, the same as GM trucks up until the mid 60's.
You might say "yuck, a Jap axle under a domestic truck!" Well, some of these trucks,(the US made ones only), in the 90's came with GM 10-bolt axles from the factory. I happen to have a GM-10 bolt rear axle under the C8 at the moment.
Measured my screwed up original C8 axle and it is only 1/4 inch wider than the Isuzu ones, and they're plentiful and only about $150 complete at the local wrecking yards. Can even use my current driveshaft. Will have to cut and reposition the spring perches to fit the C8, though.
Am going tomorrow to pick one up and we'll see.... it's only time and money.
Thanks, David

Default playin' with my rear end...

Hi.
Bought a rear axle assembly from a US-built '91 Isuzu Rodeo that was equipped with the GM drivetrain. Wasn't easy to find the correct one as the wrecking yards didn't know one from another and Isuzu used several different rear axle assemblies over the years. After laying under about 20 trucks with a tape measure I finally got lucky...
Axle assembly fit like a glove once the spring perches were cut off and repositioned. Width was much better as you can see from the before and after photos. Came with a 4.30:1 gear ratio.
Also finally found a pair of trailer fenders that will work well with the rear body.
Thanks, David

Default more wood...

Hi,
Spent today making more tongue-and-groove lumber for the floor of the rear body, and installing it. This was very time consuming as the boards had to fit together exactly and the body must be very "square" for the floor pieces to fit correctly.
I realized I hate working with wood. Still have a tailgate to do.
Thanks, David
