Re: 67-68 and 69-72 Differences
I see you're getting plenty of response, that is good, and lots of opinions, lol. My suggestion would be to determine the year of your cab, (probably 67), then go with the parts to a same year cab. This will elliminate any need to jerry-rig, cut, alter, fill, move etc. Many times I've wished for the hand brake instead of foot, mainly because one never forgets to release the hand brake, it's right there in the way so to speak. Also here is the little hump behind the rear-view mirror on 71 ONLY that I mentioned earlier. Hard to see maybe but its there. The second pic is a rare factory auxilary fuel tank switch on a 72 Longhorn barnfind. Good luck with your build!

Re: 67-68 and 69-72 Differences
The fuse blocks are different. In the case of a wiring harness you go with what cab you have. If it's a '71the Vin=plate would be a single large rectangle. A 67-69 will be two smaller plates. You can check behind the door jamb with a mirror. W/o looking at my trucks,I'd guess those e-brake mounting points are on all dashes,since '68s are no different than 69-72 other than the e-brake. It would make sense that GM would not re-tool just to eliminate a couple bolt holes that are not really visible.

Re: 67-68 and 69-72 Differences
Found this site it is pretty useful.
http://www.oldchevytrucks.com/blog/tag/1967/ So heres what I gave. 1.Truck has vin plate for 1971 2.Has no E-brake at the time but the bracket under the dash is for a 67-68 style 3. Wiper and light switch orientation is that of a 67-68. 4. Truck does has a large back window. Do all year trucks have a dome light? Does anyone have a picture of mounting wholes or how a 69-72 e-brake mounts? Does anyone have a picture of the 67-68 fuse block vs the 1969-1972 fuse block? I appreciate the help, once again. |

Re: 67-68 and 69-72 Differences
Also up through 1970 the pickups had a throttle rod. Starting In 1971 they used a cable.

Its a little hard to see, but in your pic of the underdash, in the upper right corner, you can just barely see the ignition switch, which appears to be the smaller 1967 one, used only that year, all other years were the larger tapered bowl type chrome outer ring. Everything else people posted is pretty accurate info, except I disagree with the poster's comment that the only diff in 68 cabs from 69-72 is the e-brake. 68 dash holes for light and wiper switches are punched same as 67 and NOT the same as 69-72. And as I recall, the e-brake cable exits thru the firewall differently on 67 and 68s as compared to 69-72, where the cable exits in the corner of the cab. Fuse boxes are mounted horizontally on these 67-68 models, vertically on 69-72. This is all mostly from memory, I have owned close to 300 of these trucks in the last 20 years, done many tear downs, rebuilds and part-outs, but nothing is cast in stone with Chevys I've learned, except that 68-69 Chevelle SS's ONLY came with a 396 engine. I am on my way to my storage yard and will check/take pics on 67, 68, 70, 71 and 72 trucks I have to see if there is anything I am mistaken on or have forgotten. (They say the first thing to go as you age is your memory, I was lucky, the wife went first). Good luck on your build, and contact me if you need parts/info. I am in Phoenix, AZ. (yeah but it's a dry dust bowl)

Re: 67-68 and 69-72 Differences
I bought a american wire 20 circut universal set for my 69 and it only took about 6 hours to install.i smoothed my firewall so i mounted the fuse block on a plate next to steering column and drilled 1 in hole on left side near front fender and ran all wires to head light in finder to hide,and drilled 1 i/2 holr behind distributor for starter and ign wires.very easy install wires marked very well and every thing worked 1st time.
