78, last year for such things. would be the same for any cop car from 75 later. Just took a look in the 73 book, also lists plenty of "w/o isolator" parts

on a totally separate car, here are HD roadrunner/junkyard springs on our 73 satellite w/ 8&1/4 and with isolators

Ok guys here are the results as promised!

Here are the metal spacers I made out of bars of mild steel.



Here they are installed passenger side 3/4" spacer.



Another shot:



Driver's side 1/2" spacer.



I will have to drive and see how everything 'feels'. Thanks for all the suggestions!

Looks good..Hopefully you've got enough crush to keep everything nice and tight....But I have to ask...Who's rear sway bar are you running ??? I'm not so sure that mounting bar is going to stay where you need it...There's no positive lock to keep it in the clocked position...

Yeah I thought the same thing about the sway bar but it's hard to find one for my car that doesn't require having the factory brackets which mine doesn't have as it was not orignally equipped with one.

I have had it on there for 5 years or so, maybe 500 miles of driving and it somehow stayed put. Maybe the oppposing tension from both sides keeps it centered?

Oh yeah, I seem to recall it's an Addco unless I am remembering wrong. I would have gone with a "nicer" bar but alas, nothing available at the time that didn't re-use factory brackets.

Get rid of that iso clamp junk. Get or make a spacer for the big hole in the spring perch and get the right shock plates. Just look at that set up who wants there leaf springs isolated from the axle by big chunks of rubber or poly. Chrysler put that crap on to compete with GM and there mushy riding cars.
