I'm working on this daytona, and the timing belt part # is t153 or 95153 now the issue is the effective length is 1181 mm but all the belt from auto parts places measured out at 1160 mm and I'm not able to get the belt on , please what am I doing wrong, do I force it on ?? I've done belts and chains before this isn't my first time and I've never had a belt look this short and tight it's measuring at 46.5 inches

Welcome to Allpar. The early 2.5L was a raised 2.2L block to accommodate the longer stroke. Then they went to a 'common block' which had a shared deck height between the 2.2L and 2.5L.
Cam belt length changed accordingly.
Try a T132 or even a T114. Measure them at the parts counter before purchase.

To add to the description contributor ImperialCrown gave, research shows the 1986 - 1988 2.5 liter engines had a slightly longer timing belt with 126 teeth. In 1989 the belt was shortened by 3/4 inch and has only 124 teeth.

Chrysler PN for both the 2.2L and 2.5L common block engines, other than the 16 valve engine is 4387549 so if what the parts store is giving you is too short then who knows what they have. FWIW, the old VW built 1.7L uses a 121 tooth belt and the tall block 2.5L uses a 126 tooth belt.

Now, if there is an AC bracket with slotted holes, the 2.2L and the common block 2.5L the bolts going into the head will be at the bottom of the slots, the tall block 2.5L will have the bolts at the top of the slots.
