| maybe this will learn some others something too.
Question: Did 80's/1990 9C1's have a 5x5 bolt pattern and civi ones had the other... 4.75... I think? I can't find anything on the web about it. | |

| the only 77-90 Chevrolets that had the big bolt pattern were the 9c1 and the wagons. Everything else was the 4.75 bolt pattern I believe, including cars that came with F41 suspension or whatever, although I could be wrong on that.
This goes for other 77-90 B-bodies as well. 77-84 C-bodies/85+ D-bodies were the 5x5" bolt pattern though. | |

| Not sure about the years. but it used to be 5 by 5 for 9c1s and station wagons. 4.75 for civies. My 89 9c1 was 5 by 5 .I remember not having many wheel options. My 78 aerocoupe caprice was 4.75 on the front and 5 by 5 on the rear. The rear came out of a station wagon for the gearing and sway bar. I had keystone classics with the old oval washer that you could flip for different bolt patterns. It took me so long to type this that Matt already answered your question . | |

| Thanks for the clarification guys! I'm getting pulled back in the boxy lane. So I seek knowledge. My cars are too old tho. I dont think I can own anything older besides the Monte until I at least own/pay a mortgage for a house. | |

Welcome, brother!
On bolt patterns:
Usually, if not always, only the 9 passenger wagons got the big bolt pattern.
Those cars (three seat wagons) very often had Bendix Hydroboost brakes too!
The 5x5 B/P was always part of the big brake option, 12" front rotors, & 8.5 9C1 HD rears with large drums.
Regular wagons with no rear (3rd) seat, LO3 (305) engine, no HD towing Pkg or police duty wagon, had 5 on 4.75". | |

| How rare would one of those 5X4.75 wagons be? I've never seen or heard of one.
In a related matter, does anyone know what year GM started putting Olds 307s in all of the B-body wagons? | |

I think your question has already been answered so I wont even bother typing it again. I'm seriously considering selling my white one and getting a box body lately. I want something "different" but I can't really spend the money on an SS no matter how I crunch numbers without selling my '74. lol | |

| I know where there is a decent boxy that has been modestly detailed/modded. Comes with Monte SS rims and some other looks like 18" rims. Last time I knew he wanted around 3k for it. But its been in his driveway for almost 3 years. Desperate salesman maybe. If anyone wants pics. I'll get some tomorrow. Might not be a bad ride. The guy really liked the car when he drove it everyday. I guess he needed a more practical DD. I dont blame him. | |

I actually have some pics of proof in my "archives". One is a mass state k-9 I believe! May also have been a CV wagon. I'll look. | |
