Hang on, you lifted your car with a forklift?
pickles lifted it with a forklift (not me). at the time it was a written-off wreck and they didn't give me much choice in the matter .. the weird thing is apart from the busted fuel tank there was no under body damage so im not 100% sure it was done by pickles.. may have been pre-existing but i still suspect it was being picked up with a forklift!
As for replacement tanks, i got mine second hand, was from the orange galant i wrecked a few years back (that was the main reason i bought the car! Mitsubishi wanted some ungodly sum for a new tank..)..
a PFL galant tank will fit on a FL legnum, so i would wager any PFL/FL Legnum/galant tank will work (the PFL and FL tanks appeared to be virtually identical when i had them sitting next to each other)
