Alternator repair question

[FU]

Unless there is a huge stereo (read getto blaster Keith) in the car a larger out put alt. is not needed. In other word's a high out put alt. is a waste of money. A stock alt. rebuilt correctly is fine.

Rebuilding these & our starters isn't that hard.

If they had one that would fit without surgery I was just going to get the 140 amp version. I don't have any electrical load that didn't come with the car.

I'm currently swapping my alternator to the LT1/4 style and as far as I can tell there isn't that much that needs to be done. I will have it done this weekend since that is the only time I have to work on it.

Others who have done it before can probably chime in but as far as I can tell the LT1/4 case is slightly larger than the LT5 alternator, the pulleys are different diameter, the mounting hole in the back is in a different location, one of the mounting hole on the front is smaller.

All that needs to be done for the swap is:

1. swap pulleys
2. Slightly drill open the smaller of the two front mounting holes.
3. Relocate mounting hole on back by drilling and tapping the small hole between the stud for the 12v cable and the provided mounting hole. See picture

They he said it was like $150 if I wanted it shined up.

When I had mine apart I threw it in a bead blast cabinet and hit it with some walnut shells.A rebuild should include the most important part,voltage regulator.This is a stretch but send it to me and Ill blast the cases and replace any worn parts,have it bench tested and send it back.You pay only shipping You need to break loose all 4 bolts first,dont want to fight a broken bolt.Theres no reason why you cant rebuild this yourself,theres really nothing to it.The brushes has a provision to hold the brushes in place during installation.
