65 comet polyurethane bushing kit

[loman]

Does anyone have a link to a 65 comet rear spring shackle polyurethane kit? The only thing i keep finding are rubber ones for the comet.

Prothane offers the bushings, two sizes of through bolts 1/2” or 7/16” either in red or black color material.

They are the same as early Mustang.
Part numbers : 6-1051 or 6-1052

Thanks Jim. Do you know the OD of the bushing? The webpage didnt give that dimension. The one I have is 1” od. I searched the forum earlier and it seems the od had been an issue with other people in the past. I will call them on Monday to confirm.
Thanks again for the lead.

both my 65's had different size shackle bushings than a mustang .they were right at 1'' O.D. whereas stang was about 1.5'' or something . & my car came with the larger size in the spring eye & the smaller 1'' thru the frame. but when I took the springs off my parts car it had the smaller 1'' bushings on top frame & spring eye bushings. I always wondered if maybe someone changed the springs on my blue car, because they also seemed too short,the leaf eye rode against the frame swept forward. so I figured someone put falcon or stang springs on it,because when I ordered new shackles with bushings they were all the smaller 1'' OD. that was over 10 years ago but I couldn't find anything but the rubber ones.

Is this for a street car or racecar?

This is for my 390 track car. The one in the signature pic. Since i got the rear end out and waiting for axles, i was just looking around at things and was daydreaming.

[poboyjo65]

Daydreaming huh,,,that's how I ended up with sliders from speedway. they were for a mopar & were close to same size ,just a little smaller than the stock leafspring eyes, but I made some spacers from SS to fill the gap . that was before I daydreamed my self into split mono leafspings.

I ended buying some polyurethane bushings from a offroad vehicle website. The bushings i bought were for a jeep with 2 1/2 wide leaf springs.

Man those measurements sure are confusing. it needs to say which is OD & ID . & needs to say same thing at top as it does at bottom. I like products with specs drawn on a pic of the product like a blueprint showing exactly what is each numbered measurement is on the description. but good luck hope it fits!

[loman]

Confusing, I agree. I ordered the wrong ones at first. The one in the link is the one that I put on the car. I forgot to take a picture of the poly units next to the rubber ones for comparison.

[poboyjo65]

I couldn't figure out where the 3/4 was. didnt say 3/4 at top but said 1-1/2 x 3/4 under description. maybe it was a typo ? Am I missing something ?
Glad they fit!!!

Hey, Poboyjo, thinking about your springs seeming too short, do you know what the distance between the eyes is supposed to be (for
unsprung springs)? Or maybe what angle the shackle should be at? Pictures I've seen show shackles pointing nearly straight down.

I think it would vary depending on how much the spring has retained its' arch. but mine was pretty much flattened out straight with not much arch left & shackle was swept forward when it should have been swept back a little with the leaf flattened out. the wrong bushings on it was another clue they were wrong leafs. shackles straight up & down would seem to be right to me, possibly swept forward if springs are new with a lot of arch. [JMO] tho, or guesstimation. also I think you measure a leaf not from eye to eye straight line but with tape run under bottom of leaf eye to eye so you measuring the metal because you would get different numbers for wore out de arched springs than from new ones with lots of arch.

The correct position for a leaf spring shackle is to have the leaf spring end of the shackle a few degrees tilted to the rear. The car should be at ride height, on a somewhat flat surface, and parked when checking this.

Right but new springs probably gonna be closer to straight up and down until they sag some. Then they will be like you said to the rear a little.
