I did the spectra tank with electric pump inside. It has a sump pan, maybe not the best sump pan design having radius corners verses square for fuel sloshing.
It’s $326@ ($310 with 5% discount)
1972 PLYMOUTH CUDA 5.6L 340cid V8 Fuel Tank & Pump Assembly | RockAuto
This is a 72 Cuda tank shown.
From my tank I took the pump out, it’s a walbro, forgot the model number, but if I remember right it’s a very available one with good flow.
I tore the pick up sock when removing pump assembly. Just as well because it was clocked wrong meaning not laying flat, but turned up. Would of worked but not ideal.
I added the Holley hydra mat sock, probably didn’t need to, it’s expensive but should help prevent low fuel starving. Bottom picture shows how Holley sock comes with the star pump connector. You can see from my picture I had to trim all the other ears off then it fit perfectly.
These are pictures of my tank.
