Saw this on Fakebook another way to snake around the top A arm.
Little hokey ish?
But the idea is solid

That's what I mentioned previously in post #11. The 3rd joint & requisite bearing support anchor start making things busy. Some are absolutely necessary (tight R&P set-ups) but w/these trucks it's a straight shot between the column & box. I wanted mine to look clean & uncluttered.

Sectioning the area on the arm was the better option for my 'wants'.

Been on the hunt for a set of those. Upper and lowers.
Have a set of the lowers on my c10 I like the steel bushed pivot and slightly narrow at the pivots.

My son's tig skills are getting better

I like the earlier arms myself after trying poly bushings in the later arms & not liking their 'stiction' during rotation @ times. That stiction to me = inconsistency.

That weld work on the wrench is cool. He should keep that so he can reflect on it one day when you're no longer around to tell him how proud you are of him.

@scoti

Could you help identify these swap meet drop spindles?

The numbers don't cross reference to anything on the googler

OBS spindles would be my bet.

Re: 2wd swap
 
Suppose they're the light duty 1" rotor version?

This is surprising. Was planning on reaming up to squarebody ball joints

The ball joint is bigger on a obs than a squarebody.
But the tie rod diameter is smaller by a bunch

Lower BJ for an OBS will fit into a C20 control arm but is larger than a C10 arm. Not sure of what the impact is on steering geometry.

Was going to go with choppin block arms.
The obs spindle was my band aid for the sectioned crossmember for the bumpsteer they create.
Get some squarebody spindles and have the kid braze the tie rod ends shut and ream them from the other side..
Or a heim end kit.

You'd need C20 spec lowers to do the OBS spindle (or @ least the BJ hole needs to be C20/OBS dimensions).

Also.... OBS spindles came in an HD version as well. Lt. Duty= single cab trucks; HD = Ext cab & 454SS optioned single cab trucks.

According to my mics the c20 is bigger by a bit.
They where .950 on the lower joint taper

SCOTI 04-19-2021 04:47 PM

Re: 2wd swap
 
I've only read info on the swap & haven't done one myself. I just recall the info about the use of C20 lower arms being required so it's possibly the housing size that's the same & not the BJ stud dimensions.

I've wanted to put calipers on one of each just for personal reference but haven't.

More of the good stuff.

Choppin block is kinda local so went to the shop Friday
1 inch narrow 1 inch forward

Think I maybe solved my bumpsteer problem.
Nothing like machining new parts.
Void warranty in the 1st 30 seconds

Spindles showed time to get this together

@scoti


Is there a recommendation for a bag and upper bag plate ?

See some are flat and recessed into the coil bucket

SCOTI 05-06-2021 12:10 AM

Re: 2wd swap
 
With my arms shifted forward, I made my own upper plates.
Cardboard templates of the x-member transferred over to 3/16" plate. Mounted the bags to the lower arms & marked/traced out onto the plates to understand the center-line needed for them.

The ruffstuff insert was the wrong taper.
So a good friend made some new ones with a correct taper.

Kid brazed in the new inserts my friend made for us.
Still going to need a bump steer kit I believe

So...

I think we have beat the bumpsteer

Looks good. Hard to tell from the angle though. You could always check it but cycling the suspension (especially since you dont have the spring in) and check to see how far it moves.
