S10/Blazer 4.3/T5 combos T5 question

[66 4x4]

I have a question, In the S10 and Blazers with the 4.3 and the T5 trans did any of the T5's have the Ford mounting bolt pattern? I know that the last few years for the T5 in the Camaro's and Trans am's with the 5.0 motor had a Ford mounting bolt pattern but looking for any info as to a 4.3,T5 bellhousing had this. I am putting a 4.3 in a Jeep CJ and want to keep the Jeep T5, But also want to keep the 168 tooth flywheel and the 5.0 bellhousing will only fit the 153 tooth. Thanks
