Source for IRS trailing arms?

I'm drawing a blank on exactly what you're looking for (and why it would be different from a 1970-ish VW or Porsche 924 diagonal arm).

Can you post a photo of what you're looking for?

Thanks.

Mine for a '69 VW sedan look like this - What are they missing?  A cautionary note:  the 924 uses dual spring plates per side but only year 1969 VW did the same.

Here's the same thing for a 77 - 82 Porsche 924 from eBay:

Why not buy used trailing arms?  Remember to get the weird mounting bolts. You can even use 924/944 trailing arms if you want to go to Porsche 5 bolt disc brakes in rear.  I think it was the turbos that got aluminum trailing arms.

Good comparison of VW vs Porsche trailing arms.

I bought a set from a local guy who has a bug graveyard. Had to pull them myself. Check local VW clubs or look online and Ron Lummus like others have already suggested in this and the frame thread you started.

He's asking, @Gordon Nichols (et al), because unless you know about TheSamba, or live in a market big enough to have an ACVW subculture (which is to say, "not very many places above the Mason/Dixon line"), there are not many places to just order a set of trailing arms. Doing a Google search is not particularly helpful.

It's a similar situation to the "OG VW doghouse shrouds are the best" advice people routinely give here. That's all well and good, but unless you have access to a vintage VW salvage yard, it's not very helpful.

@RobertCalifornia - TheSamba is probably your best bet for finding most of the bits and bolts you're going to need all the way through this project.

@Gordon Nichols, maybe you didn’t notice, but those are not stock control arms.  They are based on stock arms and have been narrowed.  Look where the bearing carriers protrude out the back side.

The front plate is what I noticed...

Better yet, no?

Building a VW pan piece by piece will get cost very quickly.  Plus you could buy wrong grade bolts and it could be unsafe.  Probably cheaper to buy used and refurbish. 

Current prices to shorten and build a VW pan are costly. I recently did a drum brake dune buggy chassis including a stock 3:88 transmission , ball joint suspension,  axles , 20 gauge flat floors.   Donor chassis and all new components topped $4,000.

All great links, thank you! I may be able to find what I need after all

I am starting to think in this same direction. You almost need a donor car even if you go with the tube chassis. If anything, it saves you on the nickel & diming on fasteners and the like. I'd hate to have to do that just to get this project off the ground - with the tube chassis and donor alone I'd be pushing $10k or so.
