  • There are tons of places to get pretty much anything you need depending on your skill set and budget you can save a lot of $$$$ buy welding and fabing stuff yourself such as putting in a Mustang II front clip kit rather than buy one I wish I had gone this route with my 48 Coupe. What I can tell you not to do is DO NOT use and S10 Chassis, don't get suckered into the BS like I did if your stock chassis is in good shape (mine was not) strip away the old stuff up front and IMO an Mustang II is the way to go coil over front suspension rack & pinion steering etc. using a stock frame as opposed to and S10 no body mounts to fabricate, no floor issues, no fuel tank issues etc. It was a VERY bad idea I just have so much time invested in it I am at the point of no return but if I had a clean frame available I would be contemplating scrapping the S10. The skinny is do a lot of research and profit buy the mistakes of boneheads like me

  • I have owned two 48 Plymouth coupes one a 383/727 Business coupe and one a 230 flathead/R10 Overdrive Club coupe like yours. I would strongly recommend that you rebuild the stock front suspension, add a disc brake kit (there are three that I know of on the market) and relocate your top shock mounts with some F1 Ford shock mounts or build our own.

    The late 40s Mopars already have independent front suspension that are really a pretty good design with the exception of the front shock being mounted between the upper and lower control arms. That is why I suggest relocating the top mount to the frame. I drove my club coupe as my daily driver in Dallas traffic for seven years with the setup described above and it performed great. No need to spend the time and money doing a Mustang II on these cars.

    The steering box is large and can interfere with the driver side exhaust. You can offset your engine 1.5 inches toward the passenger side just like Ma Mopar did for years with their V8 A bodies to get the needed clearance. The 1.5 inches will not even be noticeable. If you don't want to do that you can swap in a rack and pinion setup either with your own brackets or with one of the kits available.

    Checkout the P15-D24 site and Butch's Cool Stuff.

    Lastly, please keep it Mopar.

  • A proper plan prevents piss poor performance and also having to do things over. Go to a few shows on get on the internet and get some Ideas. We can help with just about anything that you need to know. Updated chassis and drive train should be he first focus. New front end such as a Mustang II. Small block Chevy are the most cost effective motors and the Chevy auto transmission. I prefer the Turbo 350 but a lot of builders like the R transmissions for the Over Drive capabilities. Just a few things to think about.

  • Looks cool, do you have a plan on what exactly the end product will be ? motor,drive train,suspension,stance. wheels, interior,paint , traditional Hot Rod,Street Rod ,Resto Mod , a big time and money saver if you're on a budget is to purchase a donor car with the parts you need ,unless you have access to a well stocked Bone yard that has early iron parts , most of the biggest 3 day car shows have a large swap meet area that can help ,the Annual Turkey Rod Run in Daytona Beach,Fl is one , they have the Spring Turkey Rod Run too,there is a lot of online sites that can assist as well as this one, most here can help , a few here have there own shop so you cant go wrong there they have been in business for a long while and can steer you in the right direction, one cool thing I see ,if you build it a custom eliminate the "B" pillar this will involve custom side glass, but it would be cool
