Thank you for the compliments, here is the write up for what we did

4x4 to 2 wheel drive conversion

This is still a work in progress but here is a rundown of what we actually did to convert this blazer to 2 wheel drive.
These are not consecutive days, just what day we were able to work on the Blazer.

Day 1 – My brother and I dove head first into disassembly just knowing that we wanted a 2 wheel driver Blazer. All of the front 4x4 suspension was removed leaving an engine hoist to hold the engine up.
Day 2 – Went to local salvage yard and purchased the front suspension, cross member, steering and basically everything forward of the firewall that was still bolted to the chassis off of a 78 C10. (We cut the frame off at the firewall)
Day 3 – Power washed and prepped the Blazer chassis and the front cross member removing only what needed to be removed for installation
Day 4 – Spent most of the day mocking up the front cross member. The frames are different between 2 and 4 wheel drive so we ended up cutting about ½ out of the upper frame rail to allow the engine mounts sit on top of the frame like it is supposed to.
Day 5 – This is where the fun stuff happens. We raised the cross member into partial position then bolted the engine to the engine mounts. Then what we ended up doing to ensure the wheel placement was correct (or at least we believe is correct) was we took the upper frame rail from the 2 wheel drive that we cut up and placed it on top of the 4 wheel drive frame then scribed the original 2 wheel drive holes to the 4 wheel drive frame then drilled them out.
Day 6 – We drilled out the rest of the mounting holes and bolted everything together on the front cross member.
Day 7 – Being that this is a back yard poor man’s build we used a flip kit from etrailer.com for the rear and pulled a few leafs out. This gave us a semi desired ride height for the rear.
Day 8 – Messed with the steering column and idler arm. The rag joint is different from 2 to 4 wheel drive. We were unable to get the correct placement of the idler arm because of constant hitting on the lower frame rail.
Day 9 – Brakes. We ordered 2 wheel drive rubber and metal brake lines to get them routed to their new location
Day 10 – Ordered 6 lug rotors from Summit racing so we didn’t have to swap out rims or tires yet.
Day 11 – New rotors showed up, went to the parts store and bought new bearings and seals for the rotors. We tore the front suspension apart and did the unthinkable. We cut 2 complete coils off and then put it all back together.

For those about to ask, we DID NOT swap the transmission or transfer case out yet. We are in the process of sourcing a TH350 for the swap then we will have a driveshaft made. The Blazer is currently sitting on 31 inch tires and is drivable.

Hopefully all of this makes sense and if you have any questions please let me know
