1 wire fitment issues

So I ordered a 1 wire alternator from jegs and went to install it and ran into these 2 fitment problems

1--the oil dipstick tube hitting the ground bolt keeps the bolt from lining up properly with the block

2--Even if that was not an issue the back of the alternator actually hits the bolt on th ehead behind it.

Is there a way around these issues, or is there a specific 1 wire alternator that has better dimensions?..Pics attached

Where is your spacer for top bolt. Any reason for 1 wire? Not a fan of them myself, but each to his own.

I left the spacer out of the picture to better see the issue.

I have been having some charging issues and wanted to run a higher amp alternator because I have an amp and just seemed cleaner.

I went a got a new voltage regulator today to see if that helps my chargning problem wiht the regular alternator

Original is easy to rebuild, Are you using a relay and battery power for amp? Maybe a simple as adding second battery or caps to the amp. Don't draw large amounts of power through in cab wiring.

When I put one on one if my FEs i had to buy a bracket to relocate it to under the head, I don’t remember where I got it but shouldn’t be hard to find. Some vehicles had it there from the factory. I have a 76 truck that had the alternator mounted on the underside also.

i personally like the one wire, easy way to up the amperage from like 45 or whatever the 1g was, and you really don’t even need to rewire anything. I think I just hooked the stock battery wire that normally goes to the external regulator to the terminal on the one wire alternator’s

Yeah I ran all the wiring for the new stereo and amp directly from battery so nothing working off stock wiring or fuse block.

Put in new regulator and reinstalled the alternator I got from Autozone a month ago(I still have the original Motorcraft that died also) and not even getting 12v to the battery when lights and/or stereo is on..only 12.2 without anything running right off the positive terminal from alternator.

On a related note does this bottom bracket look right? I would expect it go in front of the alternator not behind it.

If belts lined up and nothing twisted should be ok.

The belt lines up about 90%...100% depending on the angle you look at it. LOL

The reason I started down this road is because the truck has an odd low rpm "miss" that also happened when the original alternator went bad and eventually it left me stranded(luckily at walmart lol)....but at that same time it was showing another same behavior where the stereo would not get power for 10-15 seconds after starting the truck which it has begun doing again.

it will start smoking if it’s not, I had this similar issue. The 1 wire I bought had two different size spacers for it I think
