Fox I have an 88 Blazer rearend in my 38 and I think the dimensions are the same. It's the smaller Blazer not the full size. For the frontend I would suggest having a look here it is in Canada and close to you so you can probably save a few bucks on the exchange etc.
www.macgyvers.com I am going to get some pictures onto my site soon of the retrofit. I have the whole frame boxed in front to back as some metal gets a bit thin after 64 years.
