I have read a decent amount on TF conversions and have not seen (or at least noticed) this tank mentioned for them before.
My plan was to make a fuel door in the driver fender, but I am toying with the idea of hooking it up to the stock filler. There was a previous thread (that I can't find at the moment) where someone connected the stock filler to (fiero?) tanks under the bed.
This is a 1.5" filler. The stock one is 1.375", but I should be able to make an adapter for that.
