3800SC Low Mount Alternator Options?

Post by Red3800SC »

So after 10 years my Purple Reign alternator mount broke. The welds just over time finally got brittle and snapped. I'd say it held up and I'm in no way shape or form talking trash on him or the design. What options are available that can be purchased these days? I'm planning on fixing this and making another for a spare, but I'd like to see what other options are out there. Maybe something that can use the grand prix alternator, but I don't know.

This might sound dumb but does he not make them anymore? I haven't followed the 3800 vendors too closely. You might be able to reweld that but it doesn't look like a very clean break so it might not work well in the long run.

Cast aluminum sucks to reweld but can be done. It might be best to find a real pro and pay more to make sure its done right.

I thought someone else designed a low mount alt too? Noone else has made one?

You might have took into some custom made bracket or mount it on the firewall side perhaps with some idler pulleys and different belt routing.

West Coast Fiero makes a low-mount alternator bracket. Not sure if it's a normally stocked item or if you'll have to wait a bit (or longer).

I believe Dan, FieroFlyer makes them as well. I don't know anything about the quality though.

Yeah, cast aluminum is not the best material. I'm waiting to hear what FIEROFLYER (Dan) says. I don't know if I can trust West Coast Fiero, it might take a year to get it. I was hoping Purple Reign might still make them, but I haven't heard back yet.

Well got a friend to re-TIG weld this at his work today. Should have it up and going tomorrow. I'm also going to have him setup another low mount bracket with a v6 alternator bracket I have and a 3800 dog bone bracket as a spare or if other people might be interested, could possibly start offering these. Not sure if people are even interested in such a setup or if Shawn (Purple Reign) still offers them, but thought I'd throw the offer out there. Don't want to step on his toes if he does, so if he does I won't do them. Here's the new re-welded setup after being blasted. Looks a lot better than the painted black I think.
