I looks great. I hope its more than just the graphite and a few alumimun bits. I see that it doesnt appear to have HB front arms. Rear doesnt look right iether, but its been a year since I sold my Pro 4. Towers also look lower due to the fact your running that Mazda body and nothing is poking through.
If its a conversion kit, donor parts like bulkheads, camber blocks, driveshafts and diffs (basically all the parts that didnt transfer over to the cyclone series and tcx series cars) are almost impossible to find. Strip out one hole in those factory bulkheads and now you've got a shelf queen.
If this is a ground up design thats based loosley on the pro-4, I might seriouly take a look. I was fairly let down by the Pro-5 release and have been waiting for a good shaft drive to come along that didnt cost $500 in the used market.
If Bert mentions the TC4 here, some-one who knows him, please thump him.
