From what i learned on here Yes you can. I dont know the exact date but at some point when the 49intek came out it had better beefier rods and they are now the replacement rod for 40,44 & 49 inteks. Check my profile and check my topics one of my posts covers this and where to get the rods for $37 apiece. They seem to be working fine in my 40
Also the search function works great on here....i have spent hours using it and reading very useful info and links to all kinds of good stuff
