Good day everyone, just would like to ask if the final drive coming from a k20 type s which I believe is a 3.9 fit the type r transmission(4.7) and if the bolt pattern of the type s differential same as the type r differential. Thanks. Any suggestions of a 4.2 aftermarket final drive to fit my type r transmission? Planning on using it on a boosted 500hp k20. Any suggestions or advices will be much appreciated. Thank you very much.
