Determining 2wd or 4wd (69-72)?
What features will assist in determing if a Blazer/Jimmy is in fact a 2wd vs. 4wd?
Frame differences VIN# Tub differences What do you need to look for?

Ok there Wynne, that's the last time I ask for assistance from you. Why don't you just go build another beautiful truck...

Re: Determining 2wd or 4wd (69-72)?
2wd model key components...
frame differences - frame will be 104" wheelbase with rear coil springs with trailing arms - not leaf spring on the 4wd VIN - will begin with a C if it is a factory 2wd. If the first digit of the VIN of the truck is a K - it was originally a 4wd. front axle - 2wd - upper and lower arms and springs - not leaf spring straight axles like you find on a 4x4.. Tub differences - none. Except most of the 2wd Blazers I have found were rusted beyond belief... |

Nate,... look at the rear frame rails. They should have the same shock crossmember as your truck. Coil spring area of the frame should look the same also.

Re: Determining 2wd or 4wd (69-72)?
I think the stock 2wd engine sits about 4" forward of the 4wd. This puts the transfer case shifter in a reasonable location. I think the frames have holes for both motor mount locations but a bad conversion will still have the engine in the stock location.

i believe there is a dimple in the frame on the drivers side.

Re: Determining 2wd or 4wd (69-72)?
Thanks for the information guy's! I haven't been able to make it back out to look at the reason I made this thread.
As soon as I can get back out there and get some pics I will.
