Where to find 1970 BB Upper Alternator Bracket

Anyone have a suggestion of where to find either an original upper alternator bracket for a late production (April) 1970 Chevelle SS big block (the bracket with the three small holes in the upper left for the heater hose bracket and alternator cable, and the large hole in the lower front center for adjustment) or a quality reproduction bracket? Apparently, the hole for the alternator cable on my bracket was stripped at some point because it's been drilled out and it now has a nut & bolt to hold the cable. I want to replace the bracket so it looks correct.

I haven't been able to find an original bracket and all the reproduction ones I see are for early production 1970's cars and only have two small holes and don't have the large adjustment hole. I see reproduction brackets for small blocks that look correct, but don't know if they'll work. (I'm guessing not because they're not for cars with long neck water pumps.)

One alternative is to buy the reproduction bracket and drill in the third small hole and large adjustment. Would rather have an original bracket, but they're probably aren't too many around that don't have the same problem as mine.

Thanks, guys!

I bought a reproduction bracket and drilled a large hole to allow tightening the belt.

Thanks, Jim! That seems like it's going to be the best option.

I've got a nice original but need another '69 unit. They are the same minus the big hole, that's the reason I've kept it. If you find an oem '69 I'll trade straight across.

Why donít you have the hole in yours welded up and re-drill it? Iíd rather have a repaired original.

People donít like to have to think in high resolution. Jordan Peterson. Thatís why we are forced in to so many binary choices.

Here is what I did on my one owner 70-454. I took a nut and ground it down so it is very thin. My LS-5 has C-60 so when you are all done and all hoses ( A/C & Water) and wiring are in place.
The nut was not noticed by the Judges at the MCACN show in Chicago.
As Alan said fix or repair your ORG. piece. YES you can see the THIN nut if I tell you where to look !
