replacing bottom side roller wheel

My bottom roller size is approximately:wheel diameter 1and 1/4 inch,width 1/4 inch

mounting strip width 7/16, mounting wheel separation 2 1/2 inches. these match with your product # 23-218

but your roller wheel is made of nylon, the one i have is metal.

the wheel is for metal door 79 1/4 high and 24 inches wide.

i would appreciate your help

followup response to my initial enquiry about your product #23-218, bottomside roller wheel.
The house is a ranch house built in 1955. Unfortunately I do not know the manufacutere of these metal doors.The closets in the rooms have metal double doors, the roller tracks are 1 3/8 inch apart. The top width of each track is also 1 3/8 inches. All the roller dimensions perfectly match with #23-218. The only doubt I have is about the strength and durability of nylon wheels especially at the edges.Is it possible to have this product in metal wheel? What are the alternatives?
