The 3:55 ratio is a mathematical expression that corresponds to the number of teeth in the ring gear divided by the number of teeth in the pinion, so yes, the number of teeth matter. Keep in mind the pinion and ring gear are a matched set, so don't start mixing from different diffs or packages.

Also noticed your tag does not indicate limited slip. If you are building a diff, this may be something you wish to address.

 

Brakes look good. Not sure how much it matters, but the manuals state the cable anchor should be placed over the anchor pin with the crimped side toward the carrier plate.

 

Well I have them sitting in my closet, and I did purchase the limited slip differential. This Rear end kit my rear will now be a 3.73 gear ratio, will this do?

 

Rest assured I had to redo this one because I hadn't realize I did it incorrectly until I took the picture, it was not done incorrectly on the driver side.

 

Does anyone know anything about this truck based on my door tag?

 

Kit from Summit will do just fine.

Your axle code is 19 which is 3:55 open. Some 83's still had the 9 inch, your earlier pics show an 8.8 which will work with your Summit kit.

 

Ive already had that kit so I guess ill change it out this weekend

 

Update:


I bought the 30 gallon rear tank for my truck from LMC and have been modifying it to have a flowing & efficient manner to work with the EFI 2.0 I have. Heres what I have done this past weekend


Unboxing Aeromotive Phantom 450lph




View of the mount for FP




Cutting 3-1/4" hole (lots of WD-40 used in the making)




Cutting the hole for aftermarket Sending unit and spraying any marks made with anti rust paint




Installed both units into tank




Wiring the both units and dressing / protecting the wires with looms (had to make the connector on the FP to match the housing used in the EZ EFI Kit.

 

Lotsa work, but it looks excellent. Well done!

 

Looks good, that pump mount looks like a good "universal" mount you could use with a Bosch or other pump.

Nice Job

 

So whats the proper way to mount a fire extinguisher in the cab?
Just screw the mount right into the metal or prep the metal?

 

Its actually a whole fuel pump, baffle and mount assembly http://aeromotiveinc.com/wp-content/...x-1024x680.jpg of course more than whats in the picture. It is a very impressive system if you ask me.


Dusty is this a rhetorical question? If not Im not too sure, I was planning to have one at each door... It might suffice, all I know is Im not letting the truck burn down again!

 

No I'm serious, because I'm installing one soon. I'm asking how does one properly mount these things? I have one I've been dragging my feet on installing for a few reasons. Mainly not sure where to mount it yet.
But the next question is how, just drill it and leave the exposed metal or dab some primer over it and silicon the screws?

 

I wouldn't use silicone on fuel system parts. In my experience it doesn't stick. Maybe Permatex #2?

 

I think we are discussing the mounting screws for a fire extinguisher.
I'm not sure where silicon and fuel system comes into play here?
