Help Identifying My Chassis
 

Have a 1956 F100 on a chevy frame, bought the truck little over a year ago, now lowering it, need to know exactly what I have to order spindles and other parts, past owner didn't know exactly what chassis it came from, looks like a C10 86 or 87 to me, it has leafs in the back, here are some photos, hopefully you guys can identify it for me, thanks Richie.

Just to add, the rotor measures 12" and is 1 1/4" thick.

Cant tell from picks but if the front crossmember where the proportioning valve is, the rear most crossmember, and the crossmember between the leaf spring hangers are all solid, its a 73-80. If all said crossmembers have cutouts it is an 81-87. If the e-brake cables on the rear axle both run to the left frame rail its an 84-87. You could remove the bed and decode the vin on the top of the right side frame rail between the front bed mount holes. Also check for a vin on top of the left frame rail in front of the engine.

Re: Help Identifying My Chassis
 

^good thinking

look under its butt. if the rear most cross member has holes then 81+

Re: Help Identifying My Chassis
 

Thanks, here's a few more, cross member in front of rear, rear one hidden by new fuel tank couldn't see it, and a couple more shots from up front.

Emergency cables are cut, you can see one in the photo, there's another cut one on the other side.

Re: Help Identifying My Chassis
 

looks like 80 and earlier.

Re: Help Identifying My Chassis
 

Thanks everyone, so I assume this is a C10 chassis, so just say late 80s C10 when ordering spindles, ball joints, etc., they all should fit and doesn't have to be exact as far as year goes, all have the same front suspensions then.

Re: Help Identifying My Chassis
 

Correct.:metal:

Negative, your frame is 73-80 all though I bet the parts you will need are all classified as 73-87 C10.

Re: Help Identifying My Chassis
 

JK, little confused as to your statement, but, if I call a parts store and ask for a drop spindle, just say it's for a 80s chevy c10.

Re: Help Identifying My Chassis
 

I believe the drop spindles 73-87 just ask what size rotor it has.

Re: Help Identifying My Chassis
 

just spit balling here. any chance of it being 71-72?i belive they use different ball joints but had disk breaks too

Re: Help Identifying My Chassis
 

Your frame was built somewhere between 1973 to 1980. It is not a 1981 to 1987 frame. I havent checked but I believe all the front end parts were the same from 73-87. I think all rotors from 73-80 are 1.25in thick. When you buy parts for your frame/chassis, buy parts for a c10 between 1973 to 1980 just to be safe.

Re: Help Identifying My Chassis
 

Negative, those have screw in crossshaft bushings on the control arms IIRC.

Re: Help Identifying My Chassis
 

Thanks everyone...

Re: Help Identifying My Chassis
 

Negative. JB1 and JB3 rotors were 1".

(I happen to have the brake system release charts for '74 and for '87:

Shouldn't be a big deal, though.

Re: Help Identifying My Chassis
 

damn thats a sharp truck btw

Re: Help Identifying My Chassis
 

Thanks Keith, I thought the 1in rotor was part of the 81 and up weight reduction deal.

Re: Help Identifying My Chassis
 

Thank You..

Re: Help Identifying My Chassis
 

Next question, can someone tell me the correct replacement springs for this chassis or part number for aftermarket, came up with Boog springs number 6102, that has a ride height of 10", don't know what the original ride height would have been.

Thank You.

Re: Help Identifying My Chassis
 

Bump, ordered lowering arms, now want new springs, anyone know the difference between Moog 6102 and 6082 springs?

Or, what would be the replacement springs for this chassis, Thank You.

Re: Help Identifying My Chassis
 

Update, spoke with the tech guy at Moog, he explained how both springs work according to their load rates, both should give me the same height, the 6082s will give me the better ride, softer spring, not going off roading or loading this truck up anytime soon.:)

Thanks again for all the help so far, will post photos when done and let u all know how the lowering went with what I purchased.

Re: Help Identifying My Chassis
 

If it's a square body frame then look for a 9 digit code on the frame. Should be somewhere on the section behind the cab, driver's side if I remember correctly.

Decode

1st digit 1 = US 2 = CANADA
2nd digit is the year e.g. 3=73, 9=79, A=80, D=83 etc.
3rd digit is a check digit
4th through 9 is build sequence

Re: Help Identifying My Chassis
 

Thank you, when the temps go above freezing, will go back in the garage.:)

Re: Help Identifying My Chassis
 

Interesting, I've never seen a Ford truck on a Chevrolet frame. Usually seems the later model trucks are a little wide in the front for a transplant to an older body, but yours looks good. Post some more pictures outside the truck?

Re: Help Identifying My Chassis
 

Enjoy...

Re: Help Identifying My Chassis
 

Looks like a very nicely done Ford/Chevy truck! Thanks!

Re: Help Identifying My Chassis
 

Thank You,

Next question, anyone know the the part number or where to order the correct sway bar kit for this truck?, I see the 2 holes in the lower arm, new ones have them too, most photos online aftermarket ones have the bushings and one hole used.

Have that bar on my 99 Silverado.

This is what I think I need..

Re: Help Identifying My Chassis
 

I like to get 73-87 factory sway bars at the Upull it yards, very cheap.

Re: Help Identifying My Chassis
 

Installed sway bar today, dumb question, didn't even try, but, can this bar only be installed in one direction?

In other words, if flipped around, could it still work?

Does this look correct?, it's in and clear of everything, but struggled to get bolts in on passenger side control arm and bar is only half way to 3/4 way through bushing, other side sticks out 1/4 to 1/2", tried to adjust it, won't give.

Haven't put wheels on yet and lowered full weight on it to see how it lines up, waiting for new rims and tires.

Thanks.

Re: Help Identifying My Chassis
 

I noticed you put on drop lower A arms, did you align the cross shaft dimple on both sides before you tightened the u-bolts?

Re: Help Identifying My Chassis
 

yes...

Can't sleep when something bothers me..:)

So went out and flipped it, same fit both ways, feel better now, ha.
Once wheels go on and truck lowered, should help.

Re: Help Identifying My Chassis
 

Here it is flipped the other way, slight difference.

But still fits the same way.

Re: Help Identifying My Chassis
 

If it fits the same way flipped over and too short on the same side as before that means its not the sway bar thats off, its something else like the mounts, or lower control arms, or bent frame. Might need to make some comparitive measurements from side to side.

Re: Help Identifying My Chassis
 

My exact thoughts, will wait for tires, coming Friday, lower truck and see how everything lines up then.

Thanks, Happy Holidays.

Re: Help Identifying My Chassis
 

Thanks for all the help, suspension finished, happy with new stance, rims and tires, front end new 3" drop control arms, new springs and sway bar.

Rear end leafs reshaped to drop 3", new shocks all around as well.

Looks great!

Looks great, you would never know you were riding square underneath.
