I vote Passon because of three reasons:
1 Customer service before,during,and after the sale.
2 You only have to change a few things for the swap,driveshaft,shifter,bellhousing,speedo cable,etc are all re-used for the Passon conversion.
3 If you ever need a repair part or any type of service work done the Moparts Community is ready to help and your factory service manual is still good.
