Re: Sm465 swap
So you want a stick with the 203? That will be difficult since GM only used them in for 3 years. I've seen two. Either need to find the factory setup or get a late model 465/208 or 241 adapter, change the input in your 203 to 32, then drill and tap the front of the 203 to match the pattern of the adapter. Not sure on the shafts....
