Bought an og gold pan to turn into a racer. These cars were before my time, didn't realize until it showed up that the front end was different. Wanted to confirm this is an RPM '91 worlds front end, part # 7077? What did the conversion consist of? Found the old instructions but doesn't list the parts. Narrower front bulkhead and tower and longer arms? The rear end is stock. Would the appropriate available rear end be the jc racing long arm conversion?

Thanks for the help.
