Six pack carb inlets

[rpm 340]

I have a set of 70 auto six pack carbs. They have been sitting for over forty years. I would think original as date codes are sort of close. The fuel inlet is different on the front carb 4382. It is rounded on the edges. Is this factory? Different manufacturer, same bin ? Any ideas? Here's a pic.

I will say this, you can get a 1" wrench on the front carb, but not the other two, unless you remove the carb in front of it. I have hex head inlets on the center and rear carb. With a customized 3/4" wrench, I can usually hold the fitting to break the line free. But.... there are always exceptions!

Your carbs are correct.

Thanks for the info everyone.

All original carbs had the hex fitting on the center and rear carbs. Re- pops have the standard fitting on all three carbs.
