I'm not sure which sender will work with the wrangler tank as I was planning to do something custom, but is a stock unit fits then that might be the way to go and I'd be interested in doing something similar.

One way to tell would be to look up the specs or part number for the lock ring on the wrangler tank and also on the blazer tank... If they are the same then you'll know they fit in the hole. You'd still need to know the correct depth but it's pretty easy to mod the send to change the length anyway.
