Shan, Silent Bob is right but I think you're only going to find the 1/72 scale instructions. However, from what I've heard, the 1/72 Monogram Voodoo is practically a part-for-part duplicate of the 1/48 scale version.
If you still need the instructions after checking out the Revell web site, I can scan in my sheet and e-mail it to you.

PS. Here's the link for the Revell instructions. Just do a search for "f-101" and it should highlight the one you're looking for.
