Am I just SOL?

The aluminum center sections show up from time to time, but they are getting harder to find. Personally, I prefer the cast iron because they seem to hold up better. That is "if" they are set up correctly and a back brace is used to keep the axle tubes aligned. People have been using the cast units for years, from stock SBM & BBM cars, to race cars and that includes using them in altereds and dragsters.
