If its a big bell housing c4 youll need a 164 th, if its a small bell youll need a 157. Just a heads up, I have a converter for sale for the 164th flexplate....just in case your interested.

get a PT# off the bell housing and a pic. would help some also. is it a pan fill or a case fill where the dip stick goes? What is the bolt spread on the converter you may need a converter or a new bell the bell and the converter might not match. get a pt# and measure the bolt pattern on the converter also

Here are some pictures. It is a case fill, and i didnt see any numbers on the bell housing. The length of the red line in the first picture, from center to center bolt hole is about 7 3/8 - 7 1/4. Does this help any?

that looks to be a 157 tooth bell. you will also need to measure diagonally cross the bolt span.

Yea wrong way,a 157tooth will be 10 1/2 in. A 164 will be 11 7/16.
