Self contained toilet to a flush type toilet mod

[hilohowru]

Hello everyone!!! Been on here a little while, I am re-working a 1969 Voyager, that may be the one I have. I have a couple of pictures of it on my profile. It's a double axle model. It currently has a recirculating type toilet and I would like to replace it with a new flush type toilet. I am wondering if anyone has done this mod? Thank you for your time and Thank you for this forum it has been a tremendous help!!!!!
