Start with the Stock Drive Products online belt selector:

https://sdp-si.com/eStore/Direct.asp?GroupID=213

The SDP A 6R3 family of belts is in there.  You can buy closed
belts, if they have the exact length, or you may have to buy
open belts and a splice kit.  It looks like they have the exact
belt needed here.

Measure the desired belt length and width, or count the number
of grooves in the entire belt if you have an intact one.
(Number of grooves is for the entire belt; number of grooves =
pitch * pitch length.)  Select single sided, width, and length,
and let the part selector find you a belt.

 From the part number given, you're probably looking for
   width=0.25 in.,
   pitch 0.200 in.,
   number of grooves=47,
   belt type=single sided.
That's "A 6R 3-047025" in neoprene with Fiberglas reinforcement,
for $4.37 each.  If that's too stiff, you can also get that size
in urethane with polyester, and if it is wearing too fast, in
urethane with Kevlar.  I'd suggest the urethane/polyester option,
"A 6G 3-047025", since this is replacing an older rubber belt
and that's the closest match to older belt technology.
$4.16 each.

Fiberglas and Kevlar timing belts aren't as elastic as old
rubber belts, and you may have to remove a pulley to get them on.
Prying them on over the edge of the pulley is not recommended.
They also don't provide much shock absorption.
See "http://www.sdp-si.com/D265/HTML/D265T010.html" for
a discussion of timing belt materials.
