3 wire receptacle or 4 wire for a range

I am trying to do a little work and have an electrician check it. I have a tenant with a range that is a 3 prong 50amp 125/250 (looks like the 10-50R).

List of materials purchased:
50 amp Siemens Circuit Breaker
25 ft of 6/3 Aluminum wire
Staples
Cable Brackets
50amp 125/250V receptacle

I am aware that the code changed in 1999 requiring 4 wire, albeit after I purchased this stuff. Would it be better for longevity to install 6/4 rather than the 6/3 and have the 3 prong range plug rewired? Not even sure if you can install the 3wire, though it is an old house. .

6/3 cable is the proper cable. It has three conductors AND a ground. If the stove has a three prong plug, the cord should be changed to the four prong variety.

Out of curiosity where are your from? Most insurance companies in Canada will not allow AL wire to be installed for branch circuits.
