Re: GM350/350 turbo/NP203 or D300 conversion quest
You said it had problems with the chain. When using it as a doubler, you remove the chain housing part of the 203 and only use the low range portion in front of that. The chain housing portion is replaced with the dana 300 which also has a low range. The length should be close to what the 203 is now and I think just a bit shorter.
