Look at your trans before you decide it's not computer controlled if it's an 83 it's the 350c, unless it has been swamped out, look at it and if there is an electrical plug it is the 350c with the lock up converter,

 

OK will do where will the plug be

 

Me personally i like the look of "fat and skinnies" but I like the option to rotate my tires. Cant do that with bigger rears. I would say a 275 out back would definitely fill the wells up like you want. are you planning on lowering it at all?

 

Probly not I haven't planed on it and I know I won't be able to rotate the tires and that's fine it won't be drove a lot to matter so you think I should go with a 275 65 15

 

What will happen to the trans if I remove the computer in my car

 

Have any of you used a volley contender and how is the performance of it good or bad
