B17 timing belt - which one

Hey guys, Im just shopping for the next round of oem parts that I need and this one has me puzzled

for the b17 there are two part numbers for the timing belt - which one do I order?

12 14400-P2T-004 BELT, TIMING (UNITTA) 1 $76.53 $56.63
12 14400-PR3-004 BELT, TIMING (UNITTA) 1 $76.53 $56.63

part numbers are different, same price …

Both are for the same application.

The P2T comes on the 1999 Civic Si

The PR3 comes on the Del Sol Vtec

Same motors… they’ll use the same belt.
