Here’s a video of someone else building your kit 

Don't cut the ribs.

This is why test fitting is always a good  idea.

I would careful;ly take the lowers back off.

Get them to fit "dry" then look at why it isn't working.

I've built a Tamiya P-51D and it was wonderful. SO, a photo would help us see what your problem most likely is and we can advise on your best course of action from there.

Thanks to all that have replied. I have built a few of them and all were great. Tamiya is my favorite brand because I like kits that fit.  That is why this is so perplexing. To answer questions, first I know pictures would be a big help but I don't have capability just now.  The cockpit is not an issue, fit in like a dream. Everything had been "Tamiya like" until the joining of the wing tops to the bottoms.   I have removed the lower wing from the fuselage and will see what happens now.  I'll let you know how it comes out.  Thanks!

Gentlemen, problem solved. With the wings separate and doing some unhindered test fitting, it aappears the ribs on the upper wings, which are part of the wheel wells, are a little warped and were not sliding in to place. With a little jimmying they slide over and the wings now fit like I expected.  I can now proceed.  Thanks again.  

Yay!

Thanks again guys.
