CHEAPest way to convert rear axle bolt pattern to big bolt pattern???

It seems like the wheel adapters aren't that bad of a choice as long as you aren't taking them racing. I'm in the same spot upgrading the front to disc but will wind up with mismatched wheels for a while. To skip that headache I'm gonna try these adapters on the back for now. Not a long term fix but it seems like it'll do on my 7.25 rear. Anyone hear of the wheel adapters failing or found any other evidence why they should be completely avoided?

Folks used adapters a the strip with slicks and they held up for a while as I recall. Cracking through the lug holes I think was the problem. Also ran them on the front of the Barracuda for years with no issues. Street use should not be an issue other than checking for loosening up regularly. Sold them about 6 months ago. Check your clearance for potential rub areas.
