Stock Muffler and Exhaust Question

[cericd]

I need to replace the muffler on my 1970 C/10 which has a stock 307 with ram horns. I'm trying to keep it as stock looking and sounding as possible. Does anyone have a recommendation for a stock muffler? Also, do any of you have pictures of a stock single exhaust system on a survivor truck that I could compare to mine?

I found several old threads recommending Walker mufflers when discussing stock setups. So, I contacted Walker and they said, "I’m sorry we do not list products for your application. Try checking Magnaflow Exhaust." Which I did, and they only offer "Performance" mufflers.

Thanks
