Bend, yes, exactly. The capacitance is within the amplitude (voltage) and time (frequency) requirements. The recommended threaded hole for mounting is 6-32
Mister Wizard's answer is smack dab dead-center.
In addition...
The rectifiers in today's alternators are horribly stressed right to the bitter limit of amperage - except the alternators to not operate at the balmy temperatures that the rectifiers are rated for. No. They have to operate in conditions a hundred and fifty to two hundred F higher. Sort of like asking a Load Range E tire to operate at maximum load on two hundred fifty degree concrete.
When Big Al sold Renard Rectifier and Frank Oropeza sold Transpo Electronics to WAI, the era of buying optional heavy-duty alternator rectifier bridges faded. The golden era is gone.
Some idiot School Bus maintenance shop decided to spend four thousand dollars on an 8-9/16" frame 400-amp Niehoff alternator for a Crown bus then sold the bus because the district was offered Blue Birds.I lucked out. But I manufactired an absurd remote rectifier using 1,200 ampere 1,675 PIV rectifiers. Stud rectifiers with eight-inch long 2/0 leads with 1/2" holes and 7/8" studs. The stator studs on the alternator are 5/16". Copper 1/2" pos & neg studs. The Niehoff has two fans: an exterior rear fan and an exterior front fan. Brushless.
When a rectifier fails open or shorted the stator will overheat and fail.
It's nice to have voltage at the house batteries within a few hundredths that at the alternator output studs.
A Power Post Princess does not need an external rectifier. A boondocker would surely benefit by one. Bokndockers make frequent gasoline and grocery runs.
