Bombardier doesn't actually make a 19.5 gram pin. The heaviest solid pin is: Solid steel roller Pin 16.4 gram (Black) 504 259 600.
You will need to order: Threaded steel roller Pin 10.3 gram 504 151 700
Then add: 10 Allen set screw 1/4 - 28 N.F X 1/4 0.9 grams 365 202 000
This will give you 19.3 grams.
You could also order a Goodwin Pin Kit SKI-1323 "Heavy Adjustable Pin Kit" and use 1 long and 1 short set screw giving you exactly 19.5 grams.
