Hi! I am trying to get readings from a thermocouple using the NI 9219. The one I have right now is this NI 9219 with orange blocks at the spring loaded terminals.

However, the wires that I'm using are too thick to put into the terminals and I can't get an accurate reading. I saw that I can also buy this NI 9219 below which has regular spring loaded terminals. Could I buy the terminals below (without orange blocks) somewhere without having to buy the whole module and would they be compatible with the NI 9219 I have (the one with orange blocks)? Also, are there 6 pin screw in terminals that would be compatible with the NI 9219?
