1971 2wd to 4wd conversion build
2 Attachment(s)
Saved a '71 burb from an early death as a "Crew cab" donor body a few years back.
Now, doing a 4wd / LQ9/4L65E conversion. Sourced a 8" lifted '70 4wd 'burb chassis that was modded to fit a LWB truck. Unf*cking it so 'burb body fits back on it was step one, and rebuilding everything. Attachment 2245699 Attachment 2245700 |

I will be doing a conversion on a Longhorn. Got all my parts from a 72 Burb 4X4 that is getting beefed up.

Keep the pics coming Nav, looking good so far!

Re: 1971 2wd to 4wd conversion build
Smitty,
The rear body mounts are different in truck VS. 'Burb. I'm looking for 4wd 'burb body mounts for the #4 position(above the front leaf spring mount) forward of the rear axle. Since you won't be using them when mounting the Longhorn bed, I'll buy them from you when you remove them. Let me know |

Pass rocker complete; rotted cowl spot repaired. Damn critters...🤣

Re: 1971 2wd to 4wd conversion build
Glad you saved that. Looks too clean to have been cut up for a crew cab. I like the direction that you are taking this. Will follow along for sure.

Re: 1971 2wd to 4wd conversion build
Good job!

Spent some "nasty time" on my back with a pressure pot sandblaster, doing some underfloor cleanup. Still need to get under there and touch up some areas again this week, but looking pretty clean so far.

That thing still looks pretty clean. It would be nice to find one like that around here.... LockDoc |
Re: 1971 2wd to 4wd conversion build
Great work! I for one are very glad you saved it.
I'm pretty sure Flynavy30 will be following your progress. |

Found a full front sway bar setup off a late 70s square body to install. After sandblasting crossmember and swaybar, got it all mocked up and positioned in place. Had to redrill new holes into the frame for the new crossmember and swaybar mounting brackets. Now to order new bushings all around, and get it all repainted. Will no doubt have to modify the original style front brake lines, due to different mounting angle of new crossmember.
$50 well spent 👍 |

I was saying I was converting a 2wd Longhorn to 4WD with a suspension from a 72 Burb. I'm using the Longhorn frame and it is already leafs in the back. The whole front with mounts came off the Burb. My buddy is doing a conversion and I will see what brackets he is not using. Smitty |

Been a few weeks since last worked on the truck.
Got the section between 3rd door and rear wheel replaced. Just the outer panel was swiss cheesy. Patch panel fit reasonably well; but lower contour was more curved than original. Had to make some relief cuts to make it match 3rd door rocker contour. |

Sandblasted and painted inner quarter area. Relief cuts on front of patch made it line up with rocker nicely. Welded up patch, ground it down flush, ready for a skim coat to blend in the two panels.

Next up is right rear quarter. Lots of little swiss cheese holes to fix; especially around the reverse light area. Good thing the patch panels cover that area. Didnt get the triangular rear inner patches, but will probably have to replace those as well. Wont know til old lower quarter is cut away

Cut away the bad part of the passenger side rear qtr. Still have to trim patch panel, and cut away bad reverse light area. Then sandblast away the rust, prime and paint inner qtr arwa. Will probably take out spare tire well out afterwards and blast/repaint it.

Great work. I'm glad to see that things are progressing.

Re: 1971 2wd to 4wd conversion build
Very nice burb you saved and nice rust repair work! On the 4x4 swap, did the 2wd e brake cable mounts interfere with your shackle mount positions?

More rust repair work done. Driver's side rocker panel. Luckily the inner rocker didnt need anything other than a good sandblasting, and a few pinholes welded up. Front and rear of new rocker needed some massaging to fit; but overall an easy job.

Front part of left quarter panel repaired. Had to weld a patch for inner quarter. I'm really amazed at how much dirt gets packed up inside these rockers and quarter panels. Not sure how it makes it's way inside, but it sure gets in there.

Rocker is looking good. My Panel Truck is starting to rust in front of the rear wheel wells and has some dirt, mud, and other junk packed in there. I'm not sure how it gets in there either but I need to get it cleaned out. LockDoc |

Decided to redo the right side front rocker panel. Making a truck rocker fit a burb took some cutting and fabbing around the B pillar area. But its done; and doesnt look all that bad. In hindsight, I think it would be easier to cut the truck rocker vertically just forward of the 'burb specific B pillar area, and weld a vertical seam down the rocker...

Was lucky that the B pillar was solid; with just a little surface rust. A pass with the sandblaster cleaned it all up nicely.
