Counterweight delima
 

My 89 engine shot craps. I got a block from an 88 and swaped all my 89 externals. My 89 has an auto but the 88 had a manual. What do i need to do about the counterweights? Can i take the one out of the 88 and place it in my 89?

I have an S4 counterweight for sale if you need one. :)
