Really great looking "show room" type build. You mentioned a problem with the exhaust attachment to the manifolds. This is a normal issue with the tri five Revell kits, not serious but just the way it is. What I have done in the past is to drill the manifold outlet and the exhaust pipes so that I can slip a small length of wire in to help hold them in place for the glue to dry. Being the cheep guy that I am I just use staples from my stapler. Try a #75 or .021 drill bit and you should be close. The pin doesn't have to be very long, just enough to get the parts to stay in place. I have used this method to mount almost every small part. I haven't lost a starter, exhaust manifold or any other fiddly part since I started doing it this way.
Dave , I have heard a similar feelings expressed by others, and think from the response of others to this post you are getting a better idea of why someone might not look at your build or only visit and leave no remarks. I have a theory as to why this may be happening. I think that the reason that your post may have dropped down on to the second or third page with few visits has to do with the shire size of this Forum. This is a big weekend here, and there will be more traffic than normal. But as each person views a post and say they leave a remark, that post now goes up to the top of page one. This person goes on and visits several other posts and leaves their remarks and then that post will go to the top. The person will look at several more and leave a remark or not, but even if it's only a few more that has moved your post further down the line. Now say there are several others visiting and making remarks on some ones build . This will put you on page three very fast and no fault of your own. I'm not offering a better plan because I just don't have one. But this is why I will go at least as deep page three on my visits for this very reason. Please don't let this get you down.
I'm hardly a Ford or Chrysler expert, but what I have used is Tamiya X-14 sky blue or TS-10 French Blue or TS-23 Lt. Blue. To my eye they look close enough. For someone who has to be dead on then the factory type spray cans might be the best.
As Andy H mentioned the front bumper looks to big. The bumper its self is not so bad as the splash pan between the grill and bumper is just to large. What I have done on '56 Chevy builds is to shorten the splash pan, this brings the bumper much closer to the grill. The bumper wraparounds will then be into the front wheel opening and will also need to be reshaped. This is how the big guys do it.
