Through Body sway bar "bushing"
 

Not sure if it is technically a bushing or what you'd call it. But I took apart my sway bar to clean up before reinstalling and the part that bolts to the body with 3 bolts has a plastic 2-piece bushing on each side. Mine came out very brittle and one broke. What would these be called and where can I find replacements? Is a newer version available? Thanks for any info! Mind you this car is a 1968

Porsche calls it a "anti-roll bar bearing bracket" in the catalog. Be aware that Porsche offered front bars in 11, 13, 15, 14 and 16mm thickness.

Most are either

911S 15mm bar bushing
901 343 792 02

or

USA 911/912 13mm bar bushing
901 343 792 01

The factory never installed plastic bushings on production cars. Are you sure that the ones in you car aren't just hardened rubber? Also the '76-'77 Turbos had an 18mm thru the body sway bar, so add that number to the list that Mr. Merk provided.

Number 29?

Indeed! You need to use a caliper to measure the diameter because there are mutliple options for #29 and the catalog doesn't tell you what size each part number is

Now that I cleaned these up, they look to be 2 piece 3D printed bushings!

This is what my '73.5 looked like during restoration, the bushings were rubber...
