i just bought a rebuilt converter to go with a replacement transmssion and noticed it has 3 more mounting pads then my old torque converter.is it ok to just use three of them or should i get a different converter.also the vehicle is a 1989 gmc r3500 with a 454 and a th400.

What my old one looks like

what the new one looks like.

It should be fine.

Is it super high stall or anything?

should be oem spec or close. so you think its ok just to use 3 of the 6 holes like the original?

It'* a TC that has more than one application. So long as you have three line up with your flexplate/crank you'll be good.

ok thank you so much.i just didnt want to install it and then have to take it back off just because it would work.
