I need a replacement impeller for a 2002 GTX 4TEC 155 NA. The solas impeller is a SR-CD-11/19, Skat is a 15/20 155-83-23. I would also be willing to purchase a factory impeller. One thing is critical ......... the spline condition must be like new. I would also like an impeller with no major chips or dings. PM me or e-mail me at thompsdw@hotmail.com.
