Lca
I prefer the 1 3/8" tap method myself. For a "one off" the chisel or welded washer method definitely can work but you do have to be careful. I bought a tap off eBay using @hemi71x 's recommendation, I forget exactly what I paid for it but it was only around $20. Well worth it, especially since the LCA rebuild and Delrin bushing install is something I'm doing more than once.
As for the QA1 tubular LCA's, I use them on my Duster. Great parts, the old style added some suspension travel although the current version no longer does without modification. But not really necessary, other than the suspension travel the only real advantage is that they're a few pounds lighter. They also come with rubber bushings for some reason, which seems kinda silly to me. I installed Delrins from @BergmanAutoCraft in mine
The whole process of removing the rubber bushings and shells and installing the Delrin bushings is in my build thread here...
