okay just came from shop. got our oil seal control springs- fine. got ready to put our side seal springs in- not fine, they sent us 12a springs[which are 10 thous wider] we checked everything else and called parts supplier. they said they w next day air right springs[which are about .021. damn what else can go wrong will go wrong.

 

early 13b springs are wider too

 

Well, it's good you caught it.

 

no way could you put these in. i guess if you put narrow springs in wide grove application you would have trouble on down the road for sure.

 

You'd be surprised at what some people try to do.
