That is the link I gave you just so you knew what the part looked like.. I asked that you use the search feature and plug in "OVP" so you would then know all about the OVP , the old part#, the new part#, etc..so I did not have to type it all out for the 1000th time ..that is why we have a Search/Archieves feature. If you use it ,you will then have all those questions answered at your fingertips.
A very useful feature..I should have been more clear.

But , here ..I did it for you.
These are the numbers and you have to pull yours to see which # you have..it is on the side of the OVP..if it is the old #, change it to the one I linked you to.
And do a search to familarize yourself w/OVP , as they are a very common troublesome part on your chassis..
