[V8] New car? Ah, no.

[Seamus O'Carey]

Ok, I was trying to avoid asking about this on here, but now it's somewhat
relevant to the conversation.  I just picked up an '84 4000Q with 133k
miles.  The only thing it needs is a brake/clutch fluid reservoir.  The
problem is that the '84 apparently used a different master cylinder than any
other year (the two holes are ~3-1/2" apart, rather than right next to each
other) and it's unavailable from the dealer (they couldn't even find a part
# for it!) and finding someone parting an '84 seems to be nearly impossible.

Now I do have a master cylinder and reservoir from an '85 4000Q and one from
like a 200 or 5000 or something, but I don't know what I would need to do to
make either of them work on the '84 or if it's even possible.

If anyone has any insight (or even just a part # for '84 reservoir) I would
greatly appreciate it!

Thanks,

Seamus
