Apparently they put to different styles in my blazer. 1 and 2 piece trannys. Can you gentle man post some pictures of what your transmissions look like? Thanks in advance

 

They are quite unmistakable. There are pictures of the two different cases available on the internet.

If you have the two piece case, your bell housing will be a full circle bell housing and there will not be the earlier large sheet metal dust cover.

 

either one will work in my blazer correct?

 

Should, yes. '95 was the transition year to the PWM TCC control. You need to make sure that your current transmission pump (in front of the transmission behind the torque converter) has PWM embossed on the front of it. If it does, you are good to go.
