1966 c20 vs. c10
Hi,
I've search but not found any info on this topic. What is the main differences between the two versions? And what issues or problems would I encounter if I choose a c20 instead of c10 if renovating and adding airride, disk brakes etc? br / Thomas Posted via Mobile Device |

Re: 1966 c20 vs. c10
C10 1/2 ton vs. C20 3/4 ton. 6 lug vs. 8 lug. most aftermarket stuff is for 1/2 ton trucks unless you use oem stuff. As far as airride it should be the same but im not sure.

Re: 1966 c20 vs. c10
Will a c10 disk brake conversion fit, with new dropped spindels?

Re: 1966 c20 vs. c10
No, half ton and three quarter ton parts don't interchage. C 20 trucks have heavy duty upper and lower front control arms. And a big rear axle. C20 trucks are usually a bit cheaper to buy. If you plan on changing the suspension anyway, look for a chevy truck from 1973 to 87 and you can use the whole front crossmember setup. There is some info out there for this change.

Re: 1966 c20 vs. c10
c 20 used a the vulcanized rubber "shear" type of rear cab mount, often 1 or both are broken, they can be changed out to the c/10 style though.

Re: 1966 c20 vs. c10

Re: 1966 c20 vs. c10
he're are some pics of the truck.
How do you usually handle the 8 lug if you want nice wheels? should I rebuild to 6 or 5 lug? I guess the 8 lug is a bit unusual? /T Posted via Mobile Device Posted via Mobile Device Posted via Mobile Device Posted via Mobile Device |

Re: 1966 c20 vs. c10
Is it only the upper and lower contol arms that are differen in the front?
As I understand a c10 dropped spindel with 5 lug disk conversion will not fit? Posted via Mobile Device |

I just finished swapping a complete from crossmember/steering box/brakes/etc. from a 75 C20 into my 65 and it was a fairly straighforward process, just redrilling some new mounting holes. I'm pretty sure the easiest approach to go 5 lug would be the same thing, get a full front suspension from a 73-87 C10 and bolt it in.

Re: 1966 c20 vs. c10
I'm shipping this c10 also, maybe I should do a swap of the parts between these?

Re: 1966 c20 vs. c10
Why not leave it a 3/4? Lots cooler than a generic "slammed" half ton, IMO. The late model GM "PYO" wheels look nice if you want aluminum wheels. And there are really a lot of 8 lug aftermarket wheels with the hot-rod 3/4 diesel / four wheel drive thing as big as it is, just do a google search.
Also, a 3/4 or 1 ton with OE stuff will handle and stop pretty nice as it is. I have a '65 C-30 myself as my current daily driver. As OE a '60-66 C-20 has 40% more brake area than a C-10 does. |

Re: 1966 c20 vs. c10

Re: 1966 c20 vs. c10
Hi, cant get this out of my head.
since i have these two trucks, what is yourcsuggestion on going forward. I really want air bagged, centerline smoothies. I want to keep the big window. Since I'm in Sweden I have issues getting parts. new parts ok over internet, but its always difficult to buy used parts over phone or email in US. (Could really use a c10 friend in Indiana/Michigan for parts.) Option one: Swap 8 vs 6 lug between trucks and buy c10 5 lug konverion. Option two: Re-drill 8 lug to 5 lug? and buy air ride that fits c20. (Going to the worlds largest car meet today in Vasteras Sweden, look at www.bigmeet.com. At least they say its the largest, quite cool! 20.000+ US cars in one small Swedish city) Posted via Mobile Device |

Re: 1966 c20 vs. c10
It is my opinion, that for what it sounds like you are wanting, you would be better to change to the C10 5x5 wheel stud pattern. You really do not need the 8 lug if you are not hauling heavy loads. Also the '66 C20 will likely have a low geared rear differential (high engine rpms at highway speeds). There is basically no aftermarket parts for those differentials. The C10, 12 bolt differentials have many aftermarket parts available.
Are used parts for '73-'87 C10's available in Sweden? Quote:

Re: 1966 c20 vs. c10
Will there be different width in back and front if changing to eighties c10 set up? Will I need different backspacing when ordering wheels?

Re: 1966 c20 vs. c10
That will depend on what diameter wheels you use and just how low you want to go. I would definitely use that '85 C10 to convert your C20 to a C10

Re: 1966 c20 vs. c10
There are disk brake conversion kits for 8 lug C-20's. I think Performance Online has them. Good looking 8 lug wheels are available. I am fine with mine and don't plan on changing it. 4.10 rear end ratio is OK with me also. I quess it depends on what you want to do with your truck. If I was bagging it then maybe I would switch.

Re: 1966 c20 vs. c10
I just want to ask about my truck: Can I swap out the 1/2 ton suspension for a 3/4 ton to my C-10? As an artguy, I would like my truck to resemble the 3/4 ton I had years ago. I'm not going to haul any heavy stuff at all. I would to have 8 lug high profile/narrow wheels.
I really Dig this site! I'm very new to it and hope it's OK to ask a question and get an answer now an again. Chuck |
