B body tank in A body

Hellooooo FABO!
I have searched to no avail. I know somewhere on the forum I have seen a member cut out the spare tire space to put in a B body tank which solved a few issues. 1. mini tubbed car exhaust issue. 2. Big enough tank without putting a fuel cell in a mini tubbed car. (I think it was a fastback so not compromising the fold down) 3. Had the correct "slope" that it did not hang down below the rear valance.....

I have looked as I do not wish to clog up the forum with unnecessary chatter, but I cannot find this member for the life of me. I wish to know ....1. was it actually a B body tank that worked? 2. Are you running EFI and if so, where did you source the tank?

Thanks in advance, I know I saw it somewhere, I should have made a note of it.
