I learned a lot with this swap on my 88. When I was looking at the digital catalog I saw that the bell house was pretty much the same on 86. So it got me thinking. I hunted down all the parts, pressed in the pivot ball on my bell house and put it all together with pleasing results.
Oh you also need the transmission bearing retainer plate from an 84-86 as well. It might work without it but I didn’t want to tempt it.
On my 84 I had to swap the bell for the fuel injection. There were no more pressed in pivots left and I wasn’t about to hunt that down. 84-85 bells use a detent where a ball bearing sits as the pivot. But I was able to take a later Chrysler screw in style pivot and put it into the bell where the pivot gets pressed in and I honestly haven’t had an issue at all either.
But I’m all ears for any questions on the 84-86 external.
