Kit to install readily available PS pump on a 67 small block

I'm working on a 67 Dart with a small block and finding an original small TRW/ Thompson pump is difficult and expensive. Does somebody sell a set of brackets and hoses to install a more readily available saginaw pump on these cars? It has a cast iron water pump that exits on the drivers side, so the PS pump is mounted high rather than low like the pump on my 70 Darts
