1970 C-10 rear tank... Please help, need advice fast.

[Hatzman]

Hey guys, long time no see! So my truck is in the finishing stages... I haven't been on much and haven't posted any photos of progress... But I just got the body parts back... Frame has been done a while, powder coated and all new bolts... I will update with everything soon, but I have run into a problem with the fuel tank.

I purchased a LMC blazer tank to fit in the rear of the truck... The tank was in and everything looked great, until I placed the bed of the truck back on... The furthest rear cross member sits right where the filler nozzle is located on the tank...

NOTE: DONT USE BLAZER TANK ON YOUR TRUCK!

So I am on a time constraint now and I face a dilemma... Either I fix the tank I already have by moving the filler so it will work, or I just buy a new tank.

My problem is I don't want to order a new tank and have similar issues, so I am asking you guys for advice/help on what tank to use. I do not have many options on changing anything on the frame at this point since the truck and frame are done in regards to paint and powder coating...

Please help!
