Is an extra 1/2" worth the trouble? Depends on the tire you're wanting to run. For larger tires, it absolutely is worth the "trouble," if you can even call it that. A tiny amount of work, yeah. But I wouldn't call it trouble.
Yeah it really isn’t that bad, moving the perch is the hardest part but if you’re using a B-body rear or 8.8 you’re doing that regardless. The rest can be a bolt in operation
And the 1/2” offset is the difference between a 275 and a 295, which is more than a 1/2” of tire gain
