^ Sadly they are still in the shed unmounted. Haven't even polished the lips on the other 3 wheels yet. I've been a big slacker for sure :P . On the plus side the weather is perfect now, been in the mid 70's all week so I need to get out there.

I've been trying an elimination diet lately, still trying to cure the gut issues. Pretty much eating like a bird and feeling like crap. Better days are ahead though. 8)

With all this beautiful weather that we've been having lately I finally got out there and messed with the colt a little. I got some measurements from Dan a while back from the M&S colt and wanted to do something slightly different when I mounted my rear subframe. Instead of using the stock mount that bolts to the back of the diff and bolt it to square tubing I wanted to make a custom one from scratch. I decided to make some templates of the frame rail and reinforce them with some 3/16" plate. While I was at it I drilled some mounting holes, welded some nuts on the backside and drilled the frame rail so that it would sit flush. This not only made it stronger but it now gives me 4 threaded bolt holes to bolt custom mounts to. The bolts are 1/2-13 grade 8 bolts, 4 on each side will be overkill for a puny mount but I want it to hold up.

realized the rails bend in slightly so I cut a relief in the back, put it in the vice and whacked it a few times with a hammer

drilled my 4 holes, grounds the nuts for welding

a little high temp anti-seize on the bolts before welding the nuts on

notched the rail with a step bit and my dremel tool to allow clearance for the nuts, there was a brace on the left side that I had to work around so I tapped it back slightly with a chisel
Image

all welded in and shot with primer
Image

made a matching rectangle plate out of 1/4" steel to bolt on
Image

This will give me a strong, flat base to weld to. I'm thinking of using round tubing to run from here to the back of the diff. I will also incorporate some sort of bushing to allow for some flex. Yes I know just welding in the box steel would have served the same purpose and I could have the entire rear mounted in the same amout of time that it took me to fab this stuff up but I'm in no hurry and like to do things slighly different when possible. Once I get the rear mounted I will focus on something for the front of the subframe.

Fantastic Chris! Glad to see you are taking advantage of the nice weather to make some progress. Can't wait to see how this comes out :)

Another small update. I finished sanding and polishing the lip on the other wheel and got two of them mounted and balanced. Just need to run by Napa and get a pint of white paint to match the factory color, I already have a quart of clear left over from another job I did a while back. Now I can install the wheels and get the rear subframe all squared up and finish the mounts. I think they will look nice on there once they're done.

I think the white will look more period correct. Nothing says "late 80's/early 90's" like a color matched "Premium" wheel option. Either way, if Chris is doing it then it will be done right and turn out fantastic.

Haha, thanks Anson. I love the look of the GVR4's and the talons with the matching wheels and figured it would look good on the colt too.

Nice work Chris like always. I have looked at a bunch of the AWD builds on here and the one part I haven't seen any good pictures of is how everyone has mounted the front of the rear sub-frame. With me doing the AWD build myself soon I have been looking at seeing what can be done. When do you plan on getting to that part of the build?

Thanks Harvey, once I get something fabbed up to hold the rear diff in place and get it all squared up I will start looking into options for the front. Right now in my head I'm thinking about making cardboard templates to box it in on each side. Transfer those over to steel and weld a nut on the inside for a bolt to thread into. I have also thought about cutting the stock mounts off the front and extending it to mount up somehow to the bottom of the colt like it sits. Maybe using round tubing or something. This route would probably be easier.

My intentions were to start on the other frame rail this weekend but I keep looking at that rust forming under the braces and couldn't take it anymore. I decided to do something about that instead. I started by cutting the brace with my dremel and a cutoff wheel being careful not to cut into the roof skin.

After they were cut out I was left with the old adhesive

Image
Image

I got rid of it using my angle grinder and an old worn flap disc and then I painted on some rust converter.

and here is Rosie, she lets me know when something is on fire. :lol:

Not the original ones. I will fab something up but I'm not sure what that will be just yet. I was mainly concerned with stopping the rust for now. Believe it or not the roof is quite strong without them but I will put something back in their place for sure.

Haha, actually the cat belongs to my 13 y/o daughter Amber. But for some reason she likes to hang out with me when I work on the car. She really is a sweet cat but does get in the way I will admit.
