Identify my Rearend and Two Mystery Parts

[Stanger007]

I've got two mystery parts and an unknown rearend in my '72 Mach 1 (302). Can you tell me what the two parts are and what they do and also what size rearend I have?

HIGH RES PICTURES HERE.

What is this in the lower left???

How about this thing?

Finally the rearend

Don't know about the first 2...
The rear is an 8".

Thanks for that - I'm amazed you could tell through all the grime! I didn't realize it was that nasty until I took the pictures.

Top pic is a "thingamajig" Next looks like a circuit breaker. Last is definately an 8" rear.

You already know the rearend is an 8." Do either of the first two parts have Ford numbers on them? The first one looks like some relay for an aftermarket car alarm. Second one looks like a circuit breaker.

First looks like a 12V relay commonly used for aftermarket lights. (i.e. fog lights)
should be four or five terminals on the bottom of it. Two of them would be the coil, one common for the contacts, one NO and one NC contact.

The other looks like a electrical junction point lots of mid to late 80's Fords used them as a positive junction point.

I'll see if I can get some part numbers off of them today.

The electrical junction block is most probably what the second picture is, thanks!
