i've got an 84 TA with the single fan to cool the rad. i want to pull that fan out and replace it with the dual fans that came with the new models. Has anyone ever done this mod? How easy is it to do? Did you notice a significant temp difference when the two smaller fans where installed.

Any help would be great

 

yes many people have done this, run a search on the boards, you should find alot of stuff.
