if youve never built one..it can be an overwhelming task..lots can go wrong etc. but you can get a servoce manual and get thru it

its a W30...it deserves to be done the right way in my opinion...you can tell the new cases are different from across the street...if it where mine..i look to crash here on the site, or maybe 4 speeds by darrel in Nebraska or Iowa and get it done right and get a warranty on the work...

or buy one ready to go, and keep the numbers piece with the car..4 speed W30s arent easy to get..so anything you do to it can only help...
