When I put the 14 bolt under my Jeep, I went to a CV shaft in the rear. I changed the output shaft of the 205 to accept the CV shaft. The front was not needed. Now that I am putting the drvetrain in the Blazer, I wil just get my rear CV driveshaft extended, easy. But, I am thinking I will also need to goto a CV shaft up front. Am I correct to assume I will need to change the front output shaft of the 205 like I did the rear? If so, anything differant that I should know? Thanks, Ken H.
