2019 F-350 drw leaf spring pin size

I went ahead and added a 1” pmf bmc spacer on my new 19 dually, but wanted to add the oem rear blocks off my 06 in place of the oem 1” blocks. I removed the 1”, and slid the 2” blocks in. I then lowered the leaf back down, and realized the leaf spring pin is now larger than the older dually trucks. I forgot to measure the pin while I was there, and put the factory block back in, and called it a night. Does any one know the size of the pin head? Im just going to build me a set of blocks instead.
