YZ aftermarket tank on an 05 WR?

[sheriffwoody]

Im looking for a used 3.3 +/- tank for my 05 WR450. I know the 05 WR has the same shrouds as a YZ, but are the fuel tanks interchangable??? If im not mistaken, ims makes a 3.4 and Acerbis makes a 3.3??? I think the IMS for the YZ is a 3.8??? Anyone know what gives? Thanks.
