Coil spring insulators.....?

Hi,
I'm in the middle of instl. a after-market 4-wheel pwr.disc brks kit on my 68 Chevelle (383 sbc. 4-spd.Muncie) As well as 2" drop spindles + 1.5" drop "Moog" coils. I'd like to freshen up my suspn. w/polygraphite bushngs, but the car already has fresh ball-jnts. tie-rods. & links, I need to order a partial kit. I'm uncertain about coil insulators, there seems to be several options w/ordering kits. Some come w/front upper coil insulators & rear lower coil insulators. In general, dont front & rear coils both need upper & lower coils insulators? Or do front coils only need lower insulators & rear coils upper insulators? Do insulators really help coils from squeaking or am I wasting my $$$ ?
Thanx for any/all replies..

Front coils only need upper insulators because the bottom end of the spring is wound open ended, the end of the spring actually hooks into a notch in the lower A-arm, preventing spring rotation at that end. The upper end is the flattened end, so an isolator with fit there.

Make sure when you install the front spring to get the lower end clocked into the A-arm correctly.

For the rear spring, the reverse is true, the bottom end is wound to be flat, and the upper end is often the end left wound open.

T.Y,
That's exactely what I needed to know. Funny how little to no instr. are shipped w/lots of aftermarket components..I guess they assume if we know what it is, we w/should know how to instl. it w/out a clue. Maybe its just me, but I'm not embarrased to say I prefer reading directions...
peace, Alan

With the stuff they have out today for the GM A body, your going backwards with Poly.. Stock rubber is even better then Poly....

I have stock (1962 Pontiac) solid uppers and Nylon lowers in the front with Currie Johnny Joints in the rear four link one of the best modifications I made to my car and it rides better..

Check out the Pro Touring board... Suspension

Thanks,
It didnt occur to me that GM produces newer/better rubber for suspn. related compnts. w/is kindda of "backwards" of me to assume Polygraphite is the better upgrade. I grasp what ure saying, poly. just may be overkill on the street & may cause a uncomfortable ride and/or handling...come to think of it, if GM OEM rubber is good enough for new camaros/vettes....it's probably good enough for my 68SS
Thanx for the enlightment.......A
