Distributor eclipse 2000 GT?

I have an Eclipse 2000 GT (V6) build in December 99 and it needs a new distributor.

I found a couple in ebay, but there's a little thing Im concerned about. Some said:

Thru 4/2/00 or From 4/3/00

I understand this mean the building date, so my car would be Thru 4/2/00.

The distributor my car have says in the label TOT57871 and the cap have the wires plugs horizontally (on the sides). http://www.ebay.com/itm/WAI-World-Power-Systems-DST49602-New-Distributor-/270936758358?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A2000%7CMake%3AMitsubishi%7CModel%3AEclipse%7CSubmodel%3AGT&vxp=mtr&hash=item3f1516d856

The one I found in ebay says on the label TOT57671 and the cap have the wires plugs vertically (On the front). http://www.ebay.com/itm/300693611237?item=300693611237&viewitem=&sspagename=ADME:X:AAQ:MOTORS:1123&vxp=mtr

But both items in ebay said it will fit my car. The biggest difference is the price (130dlls less) and the bulding date.

My questions are:

If I purchase the distributor with vertical plugs, will it work in my car if I exchange caps?

Is that the difference between Thru 4/2/00 or From 4/3/00? the caps?

Thanks in advance
