Correct Alternator for '68 Dart GTS

Plain and simple .... You have the wrong alternator brackets for a cast iron water pump.

This kit is for 70 and later Aluminum water pump

This is the kit you need

Note the triangular bracket is flat.

The spacers are numbered as in the photo i posted in post #2

The adjuster bar goes into the lower of the 3 bolts that hold the bracket to the water pump. Like you show in post #1

Something to note.....

Some of those bolts if too long can crack the front cylinder wall, and use Thread Sealer on them, at least 2 go into the water passage
The brackets that you say i need are the ones I have. They are correct for a '68 Dart with a cast iron pump according to everything I've found in articles on FABO. The plate piece has 2 holes to mount through the water pump into the block and one hole to mount to a threaded boss on the water pump. This bracket piece has a curve in it that curves toward the engine when its mounted. There is a short spacer that goes between the bracket and the water pump boss with that short bolt. The only other hole in that plate is where the alternator mounting bolt goes through and into the chlinder head. The adjuster arm bolts on top of the plate bracket, and it has a crook in it to space it around to the front of the alternator where the adjustment bolt goes in.

Given all that, I don't know why you say I have the wrong brackets.
