The application chart on that ebay listing is generic and is wrong, if you have a 1998 dakota r/t then these will fit if they have a ev1 connector, I run a set in my 1999 dakota r/t, and I have an extra set if someone is interested, in 2000 they changed the connector to a ev6 style, which is the style in my durango r/t. 1990-93 is way off base, 90-91 was still LA style block and TBI injected for the 318 and for the 360 up to 1992, thats when dodge came out with the magnum style blocks. 1992 for the 318 and 1993 for the 360. Hope this clarifies things, so being you have a 98 dodge then you have the ev1 electrical connector for your injectors.

 

Mine are the same type injector other than the connector being shaped different. '92-99 have the EV1 (retangular shaped connector) and the '00 + have the EV6 (oval shaped connector).

If you'll notice the body of these injectors are plastic as where the stock injector body is metal. You'll have less heat transfer to the fuel with these injectors.
