14 bolt SF questions

[Janitorjim8]

So today at the junkyard, i was looking for a 10 bolt just to get in my truck because i need to get it running again (had 3.42s) Found 2 10 bolts, one under a K5 and one just sitting there from a 92 truck. Then i stumbled upon a 6 lug 14 bolt , figured it was a SF from what i have read here- it was on a 3/4 ton 2 wd truck, probably a 88- whenever body style. Im gonna go get it tommroow probably, but will it bolt right in or will the spring perches be different? i know i need the conversion joint i will just search for that. I have to see what gears it has also- hopefully 4.10s, then i will upgrade the front too

Sorry, it's not a bolt in, the spring perches are different. there was an article in a mag about this waaaay back, the width is okay, but they moved the perches.

Whats involved in moving the perches in- im sure just cutting them off and rewelding them right? does anyone know how much they have to be moved

I dunno about where they go, but yes, you would grind them off, then reattach them wherever you need them. You would also be able to rotate your axle to correct any pinion angle problems you might have at this time.

Measure the overall width... the 2wd version is quite narrow... ~63-64" or so. IIRC, its the wider 4wd most often swapped into th eolder rigs.

4.10 would be extremely unlikely. 3.42 or 3.73 are most common.
