I'm looking for a old school set of ladder bars. I have a 37 Plymouth coupe gasser. 32-48 inches. Thanks.
I used these: https://rjays.com/shop/ols/products/rjays-rear-ladder-bar-kit-dropped-crossmember-fits-1928-40-ford They're 46.5" long. The gusseted lightening holes look cool and reduce your quarter mile ET. Also, RJays is a HAMB Alliance vendor.
Buy some square or round tubing and weld them up. Going to need to weld brackets on the axle anyway, so you must own a welder? I've made numerous sets for different gassers I've built. Some round tube, and some square tube.
