2wd swap
Recently got a 1982 2wd K5 jimmy
It's apparently been hit in right side hard at some point before me. Frame is junk since found a 83 4wd frame. Current state of confusion. And since we're into it this far. Planning on a 1-1-1/2 inch section of the crossmember some tube A arms and bags. Rear bagged 2 link Is it possible to move the crossmember forward much without getting into the steering components? BTW I'm really thinking these p-19 pins do more damage than good on these trucks.

Re: 2wd swap
Yes the bagged truck i helped a kid build was fine that way. Although some people do have to slide the box forward too.
Incase you did not know. 4x4, and 2wd steering boxes are different. Something about different angle of operation. |

Re: 2wd swap
Tie rods on the bottom of the steering arm with a bumpsteer kit is the plan for that.
Or a obs spindle which would accomplish the same thing. As too the steering box I'm using our existing box. The donor 4x4 box was gone.

Re: 2wd swap
Looked at a few Z ing threads. Not feeling that at all.
My 17 year old got this pos jimmy and a tig welder. So the possibilities are endless.

Re: 2wd swap
Understandable. Some people won't cut a frame. I wouldn't either if it couldn't be done w/o retaining full strength.

That isn't my issue with the Z my 68 was cut and stretched in like 74 I'm told. Frame would need cut twice. The z and then the core support. Plus the engine mounts are all different. Pass Mild section drop spindles Move the lower arms forward will achieve the look I'm after. Appreciate the info. This low low stuff is new territory Always been a clip 2 coils and a flip it on all my C-10s

Moving the entire x-member forward starts encroaching on the steering box/Pitman & Idler mounting centerlines. My dually has 3" spindles, a 1.5" sectioned x-member, & PB tubular 1" forward lower arms w/bags. Previously it used .750" forward GM a-arms w/coils (1 coil removed).

Re: 2wd swap
I wasn't sure about the x member or the A arms.
Just want to avoid the wheels back look. With the 1.5 section you did. Was the steering input shaft into the left upper arm. Looks like they might hit.

The driver side upper from a 63-72 or 73-87 HD truck will clear w/a small c-notch. The HD bushings have a smaller footprint/OD & will clear but the a-arms front 'leg' still gets close when cycling through suspension travel. A small notch allows the required clearance. Another option is to use a multi joint shaft assembly to clear. It would require a center bearing support. I did the notched x-member/notched HD bushing arm approach on mine as it's a cleaner look w/minimal extras (& recommended them to the people I sold notched x-members to).

Re: 2wd swap
Nothin' to it but to do it. I would agree he's getting it done.

Re: 2wd swap
I had to do spacers on my old '68 when I did my first x-member so there's that option. What about tweaking the flanges slightly? Could that help?
On that set-up, the notched x-member & MM towers used were from a Square & placed between the 68's rails. I used some aftermarket tubular MM towers & made spacers to make up the difference. Unfortunately, I never checked the fit of the stock Squarebody x-member/MM towers before I started the mods.

Re: 2wd swap
We didn't check them either.
Those brackets where laying on the floor of the blazer when we got it. If I vice gripped the top to the flange and pulled the bottom down with a C clamp it would come. But nothing lined up. We where mocking up the fit after bolting the crossmember down.

Re: 2wd swap
I havent had a problem with the towers not fitting when I sectioned a couple crossmembers. Assuming you did the crossmember correctly I would guess that the towers are off a different generation of truck. Did you try flipping them side to side?

Flipping them made the mounts go sideways. @scoti We'll try that next if nothing else cooperates

Re: 2wd swap
Unbolted everything let it relax.
Gave the top flange some attitude and it's a bunch closer

Re: 2wd swap
3/16 spacer was the answer.
Wouldn't cooperate with a ratchet strap pulling the rails together. And I have no idea how the nuts got doubled up like that?!
