T221/sm465 swap from T221/3sp - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have searched and found a lot of information around swaping in and out sm465's but most of the info had a 205 as the tc. Can I assume that a 465/221 combo will fit? I undersdtand the clutch changes, but as far as the TC back the existing drive shaftes and cross members should be reusable? I want to make sure I know what I am getting into. The 465 is already connected to the a 221 so the adapater most be correct. I hoping just to remove the 3sp and adapter and bolt in the 465 with its adapter. After rebuilding the 465 first
Thanks as always,
Don
