Speedometer/transmission issue which instrumemt cluster to buy.
 

So I am having the same inermittent speedometer failure problems as others with the shifting issues and ABS light. Ive decided my best bet is to replace the instrument cluster with a new one but I am having trouble deciding which will fit my vehicle. The only part that is making me hesitate is the one saying "with front compartment" or "without front compartment". What does that mean and how can.i tell if I have a front compartment or.not? Any help would be greatly appreciated as they are not cheap and I have to orded one offline so I dont want to have to pay more to return it plus add anymore wait time.
Almost forgot I have a 2002 Chevrolet Blazer LS 4x4

Can you provide a link to the two types of instrument clusters?

I was able to replace mine with one I got from a wrecking yard from another AT equipped Blazer of the same year.

I added the links to the two types I was looking at.
