Haven't really decided on the tank yet, but it will be between the framerails in the back & needs to have an in-tank pump (it'll be EFI, don't want an external pump). I'll have to look at the 67-72 Blazer tanks. I've got a 90 K5 I can use for comparison on tank size as well.

What I know....
The Square Blazer tanks:
*Def fit.
*Came w/OE in-tank pumps for the final year models.
*They have a big foot-print.

67-72 Blazer tank:
*Fit between the rails.
*Might be available aftermarket w/an OE style in-tank pump set-up.
*Smaller foot-print but possibly slightly lower vs. the Square-body model.

1st GEN f-body rear tank:
*They fit between the rails after some trimming.
*Available aftermarket w/OE style in-tank pumps.
*Smaller foot-print & possibly as shallow as the Square-body tanks.

Just some ideas as I can tell you're no stranger to this.

Thanks - If I had a brain I would have done a quick test fit with the K5 tank when I had it out to replace the fuel pump a month ago lol (I kind of figured it would be too big). I'm definitely not sure on what option I'll go with, I'll probably look at it after I get through the cab rust repairs..... The first gen F-Body one might be a decent option, I think I can get one from a friend for a test fit.
