The 74PI is available on the website, but it still is not clear on the website. We are working on that part of it. If you go to the PTIF part number, the 74 PI is the .650, .550, Dozen choice. If you click the .650, then the only second option you have is the .550. That is the 74 PI. Again, we are working on making it easier to identify and order.

.550x.650 sku is PTIF-650-550-DZ
72pi and ma0300 will fit also.
I used the 72pi, minimal finish required.
Looks like they changed the part number and the website is still kinda jacked up.
