I own a couple, and the look like they'll hold up fine.
One of my 350X's, I made a small change on the swingarm in order to run an 86/87 200X slider because they are the same as a 300EX (I believe) and still available. Very easy mod that works if you don't need to have the same exact 350X part. So, I have like 5 spares.
I also have 1 NOS slider in my goody box.
When I swapped out to inverts and a 450R based rear end, I had the best parts of my 350X with the 86250R front end, so I gave them to it's other brother, lol.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
