The shifter mounting plate has the nuts welded to it so yes. It's a matter of drilling the wheel mounting plate to accept the screws.
You will need to counter sink the mounting plate too as the wheel base will sit on top of the screws.
If your current mounting plate is shorter across the width of the wheel base that could cause a problem.
Is the DFGT footprint the same as a G27. I'm not sure.
Are you really saving that much by not having the proper mounting plate?
