Looking for 6 clear plastic covers for the battey poles

In spite of the picture, a heavy shaped rubber block belongs over the + battery pole and cable end. Looks like it might be under plastic cover. IMO the plastic cover doesn’t belong. Frank come in, over. G
Here is pix of rubber block. One in place the other upside down.
The low mileage, original '70S car shows what looks to be a black plastic cover. It could be the "rubber block".
Is there a source for these?
I just checked and Stoddard shows them. I learned something new....Thanks
The PET show (2) of these so I assume (1) for each positive terminal??
My OPC dealer thinks that the plastic cover goes on top of the rubber block. The rubber block alone has carbon content so if it rubs against the chassis and gets damaged you can get a short (this happened to me). The plastic cover over the rubber block should stop this.
That’s what the PET shows. The rubber Block is covered by a plastic cover. The PET shows this only on the positive side, not the ground side. I’m curious if both need the rubber block and the cover.Quote:

I'm with gled49 , some of the original Porsche batteries simply did not have these clear covers . The 700 mile '70S of course has a newer battery that has the cover . Bottom line - the cover came with the battery , it was not a Porsche part .
The image from edition II 9.72 factory spare parts manual (original paper copy so not muddied or having doubts by suspercession etc that can confuse originality questions if using www PET as a snapshot in time --although probaly not different in this instance ).

Seems likley many got lost or tossed due to battery changes over the years. When next at car storage I'll post picture of ones for my 12/72 car although someone will probably beat me to it if someone has an original pair of the positive terminal covers handy.
Hope this helps

Paper version sometimes misleads e.g.in this case not totally accurate data point for all model quantities since some homologation RS from early series depending on conversion order only had one battery!
On the 2 original cars, my observation is the plastic covers fit poorly over the rubber blocks. G
True, but do those "original cars" still have their original factory batteries and carefully aligned leads -- if not might that contribute to the poor fit of the positive terminal cover pairing when viewed today? Not arguing it looks a great fit solution but from parts catalogue the pair illustrated /listed it does appear to be the correct to have two original factory parts and are similar to two pairs have from memory although haven't looked at them really close.
Aren't today's plastic covers black?.
When I sold tires and batteries for a living in the late '70s through the '90s, replacement batteries with recessed posts for German cars all came with those covers. They were considered part of the battery, not a replacement part from the car manufacturer. VW and BMW batteries all came with new covers. Probably Porsche batteries as well, but I can't recall selling many Porsche batteries in those days.
In the parts book illustration I posted there are two holes in battery and corresponding pips. Probably helped secure the uppermost.
Coincidentally I was trickle charging a VW factory supplied battery today from a current golf family runaround it has the same two holes on that position. Think it is the same 063 battery but didn't look carefully.
The cover items in question do have part numbers in the original 72/3 paper oarts catalog as pictured above 999 .....and 901..... numbers. Presumably they could've been ordered using those back in the day?
The parts seem available from Porsche today but uppermost one is a suspercession and think it is now black therefore to op maybe not excally as it was in 73 if important.
Folks have obsessed over equally small details here so originals in correct colour and material quite best if not binned at first battery change back in the day!
.............photo of one original pair as promised ....Attachment 487112
regarding fit..the uppermost white plastic one has a integral clip on one edge for the lip of the battery and as mentioned a pair of locating pins/pips about 1 cm long on other so the factory battery had and any replacement ought to have corresponding lip/holes to locate it securely. The parts illustration and the later Moll battery have those locating holes on the surface in the former case just for positive terminal which makes sense as this is to help protect against a short in the confines of battery boxes.

It is not actually clear material it is white slightly see through hard material illustrated in second shot. I wouldn't like to bend it at the "hinge line" these days without warming it as it might snap but one-time was probably more maliable to allow it to be flipped up. The one in OP appears to have yellowed compared to my white opaque example pictured here or probably a different colour material batch.
Hope these photos help as I suppose many of the original pairs have gone missing. I've seen various "Heath Robinson" attempts to wedge insulating things in the space to give some sort of short protection given the proximity of the edge of battery box to the +ve post and terminal block. Others no protection! I guess those folks who did that assumed it's only 12v so didn't give it much thought ... Hmm
