Thank you for your comments!
I haven't figured out how to respond to a particular member on here yet so I apologize for that.
Yes the rear end is shorter...IMO it's a little too short and I'm not entirely happy with it. It looks "bobbed" right? Some friends came over and said I could add a custom spoiler on the back and make custom brackets that attached to the tailgate/back and it would help and I'm thinking of making a template to see how it'd look.
Some of you are wondering why I took-on a huge project like this especially with just the V6 in it. It's a long story but in a nutshell I'm retired, kind-of a hermit, no wife/girlfriend and don't have a lot of cash. I've always worked with my hands (cabinet maker).
I bought the 05 Mustang and a bagged mini truck from a young guy a few blocks away for $1,300.00 (800 for the Mustang and 500 for the mini-truck). I drove the mustang home (it was hilarious seeing it go down the road in such a wrecked condition) and towed the engine-less mini-truck home. I was going to put the Mustang V6/tranny in the mini-truck and scrap the wrecked Mustang. At the time I was finishing up my 1 ton dually 4x4 truck project so the latter sat in the back for almost a year. I was done with projects and "needed" something to do in my shop so figured the Mustang already ran and drove, had a good interior and it wouldn't cost a lot of cash to "do what I wanted to it" lol. So far I only have about $2K invested (steel, tires, welding gas and some Pick-a-Part parts. But hey, I'll have the only newer Mustang Truck in the world right? hehe. I just like to learn more skills, keep busy and see what I can do. But to be honest I've been wanting to go camping and fishing!
I'll post some pics of the last street rod I built that took 4 years, and the 1 ton dually project, and the jeep project I did. peace
