I just received two 3304’s that need new blocks. Serials are 83Z12823 and 83Z12824. AR 1W-3874
I found two blocks on eBay same part number 7N-5454. I see cat has a new number 1N-3574. I’m checking now to see if they are oem cat blocks. I’d prefer to avoid aftermarket.
Are there any differences between the two block numbers I need to be aware of?
