I have an '81 Malibu that originally had a 4.4L V8. I bought the vehicle recently and it has a 350 service engine in it. I removed the OE exhaust manifold(s) and installed a set of headers on the engine. However, now I'm having trouble getting one of the brackets for the A/C Compressor & Power Steering to attach to the engine (see attached photos). Does anyone have any ideas and/or suggestions? I tried a bracket from Summit, but that did not fit/work. The OE bracket will not fit over the exhaust header tubing.
