On Barn Finds recently - maybe the most complete and solid 79 Grand Prix I have seen. From my recollection, the universal G-Body replacement door panels and consoles don't look like the ones in this GP, so this car in this condition may be "the one" for someone who wants an all original Grand...

I have the following components removed from my 79 Cutlass when it had 39,000 actual miles on it: 260 V8 diesel engine Auto transmission, not sure if it's a 200 or 250THM 7.5" rear axle, 2.41 gears was reported as stock for the diesel All were fully functional when removed. They have been in dry...

My car (see project Diesel No More) is heading for minor paint and body work soon. I am curious whether i could remove the painted strips between the door windows and rear quarter windows. The body color strips look like they are some kind of plastic or composite and slide into clips or...

I have scoured on-line sources, but I am not finding any charts that match up to the stamped codes on my rear axle, so hoping someone can help me here. This axle is definitely an 8.5" G-Body axle - it has the squared off tabs at bottom. I bought it believing it to be a 3.73 non-posi, out of a...

My 1979 Cutlass had a 7.5" rear axle. As part of drivetrain upgrade, I acquired an 8.5" rear axle from a 1984-5 Hurst Olds. The '79, 7.5 axle had 7/16" lugs, the newer 8.5" has metric lugs. I ordered Year One 17" Olds SSII wheels with 7/16" lug nuts. It appears the 7/16" lugs from the...

Installing a 6.0 LQ9 into my 79 Cutlass. I don't care for the coils bolted onto valve cover looks, so seeking input on coil relocation options. I find several relocation brackets available but very few with pictures as installed. I'd like to keep the wires short and coils accessible, so...

Has anyone out there actually purchased and received the Year One Olds SS II 17" wheels in the 9" width with 4.5" backspacing from GBodyparts.com ? I ask this question because Year One does not show a 4.5" backspacing 9" wide option on their website. I would prefer the 4.5" backspacing 9"...

I don't have the mechanical skills or garage space to do all my own work like many of the guys in the other build threads, so I will just have to share what I can before and after my car goes in to the professionals to get the major work completed. The short backstory is my first car was a 1979...

My car is a 79 Cutlass, so it has the old style 2 sealed beam headlight set up, with each headlight having both low and high beams. They are very dim, so I'd like to upgrade to H4 or LED, but I'd like to keep the old school look. I do not want any halos or multi-bulb look, and I'd prefer a glass...

I am expecting the call in the next couple of weeks to bring my 79 Cutlass Calais in for the drivetrain swap. I am, of course, excited to finally get this done (6.0 LS (LQ9) & 4L80 for those that are curious) but I am not sure what to do with the current drivetrain. The 260 diesel is in solid...

It seems like every other ad or story claims the rarity of the car, trying to hype up the value. 1 of 1,500 high performance editions ? OK. 1 of 675 made with close ratio 4 speed ? Again, I get it. 1 of 3 made with chartreuse interior and butt-ugly stripes ? There is a reason it is rare...

As I've posted about before, my first car in 1984 was a 79 Calais w T-tops, and earlier this year I bought another with the intention of making it what I always wanted the original to be. While I'm waiting my turn for parts and my mechanic's time, I'm just curious if any of the knowledgeable...

I thought these spring steel clips would be easy to find, but so far, I'm not finding them online. Alternatively, how can I get the ones out of this old panel so I can put them in the replacement panel?

I am looking to upgrade the radio in my 1979 Olds Cutlass Calais, but don't want to buy a modern touch screen or a single DIN. I have acquired the radio bezel/trim from a 1986-7 with the 1.5 DIN size cutout, so I can go to that size. I would love to have both a cassette and CD player, but I...

I am considering the Dakota Digital VHX gauge cluster for my 1979 Olds Cutlass Calais. Anyone have feedback on Dakota Digital gauges? From looking at their website and manual, it appears there are a couple of switches that I would have to mount somewhere. Anyone have any knowledge on that...

I just took delivery Monday of this very original 1979 Cutlass Calais with only 39,000 miles. I searched for one to replace my first car, the brown Cutlass Calais in my avatar pic. Missed the opportunity to submit it for last months "Most Original" G-Body of the month contest, but she is very...

I've lurked here off an on for a while, but the urge to return to my G Body roots has gotten stronger, so I am spending a good bit of time re-educating myself about the car I loved in my teens and early 20's, as I am seriously contemplating getting another. My avatar has a partial pic of the...
