Also, do you know a cheap place i can get replacement chrome for the fenders? It seems that the previous owner let all of it just start falling off.
Thank you,

Do you mean for the bumpers? Any electroplating that has to be done isn't a cheap exercise.. From memory it was around $300 to do a few large items like the zed bumpers.

no this is for the rounds in the middle of the fender on the outside edge.

just tagging onto a common thread... ::)
when we dropped in an L28 into my 240 around 5-6 weeks ago, we also kept the 280zx alternator. The gremlins have been draining my battery !, I bought a brand new battery 2 weeks ago thinking my other one was stuffed and now this one drains-out over the period of a week or so..
ok, when the alternator was installed (the one with the built-in reg), we ran a diode leading upto the back of the "T" on the Alt....pretty much as per Dimitri's tutorial, and we looped wires on the connector that fed the existing regulator, & then removed the old regulator.
I think the battery is draining itself when the car is running...I cant see how it can drain when the motor is off. any thoughts ? could my Alternator have caught the centryphical virus  :(
FYI..note: the last pic shows 2 new wires looping into the existing regulator snap-plug, which effectively by-passes the 'existing" regulator, which means you can turf-it out..

Have you checked the charging voltage yet? Is it around 13.8-14V ? Your pics are like what I did to mine.

Dim, do you mean checking the battery while the car is running ?

Yep, also disconnect that new wire you installed with the diode and let the car sit and see if it flattens the battery.

will do...
also the diode we used had a slightly different code number than those 2-3 specified..(no stock at electronics shop), is that a possible problem ?

Dim..
after we spoke, I let the car idle and the battery dropped 0.3v in 15mins....It started at 12.4 went to 12.1 before I turned it off. (no lights etc on). somethings not quite right  :(
could the regulator within the alternator be stuffed ?
I'll take it for a run tomorrow and I'll check the readings before and during..
