Have you got your old one out yet? It should have the large 168 tooth flywheel?
I'd guess the 10 1/2 clutch and pressure plate would bolt on, I doubt the 6 had a different flywheel or bell housing than the V8 so it should fit. With the inspection cover removed, can you get a casting number off the flywheel? I used a flywheel and bell from a 58 348 when I converted my 283 powerglide to a 4 speed. Outside diameter is only 1/2 inch bigger on each side, so should be room.
I'm not knowledgeable on the 6's.

I'm going by the 1959 Chevrolet info, but it appears that all engines came with the 168 tooth flywheel that year. Clutches were 9˝" standard with the six and an 11" was an option on the inline six. 283s used 10" clutches while the 348s used a 10˝ clutch. Six damper springs on inline sixes with either the standard or HD clutch. The V8s almost always used 12 damper springs that year.

What size is your flywheel? Post a pic of the face of it.
I still think the stock 10 or 10.5 clutch will bolt right in. Pick one up for a 283 from Napa or Canadian Tire, return it if I'm wrong. Likely $100-200 for a "kit".

Looks to me on your bottom picture like that flywheel would dress out to 10.4? It may have been factory surfaced to take the 9.5 clutch, but has room for a bigger clutch? That outer ridge would machine off, take that pic to your machine shop?
My parts book shows a flywheel #3705409 for 1958-1962 261 (235 too) with std clutch, not HD. After 62, it was the 153 tooth, pre 62, 168 tooth.
A google search shows a reference for that flywheel that says- 1956-'65 cars and trucks with 10 or 10 1/2-inch clutch and 11 5/8-inch bolt pattern- Flywheel #3705409

Many thanks gents. Interesting article supports what youve said. I think the next step is to confirm what flywheel I have.
Chevrolet Flywheels from Hemmings Motor News October, 2011 - Jim O'Clair Finding a flywheel to fit your Chevrolet in the mid-Fifties used to be simple: There were only two possible units from 1942-'53. One flywheel (#3705385) covered all 1937-'53 cars and trucks with a 9 1/8-inch clutch disc and a six-bolt mounting pattern; the other (#3705387) covered all 1942-'53 cars and trucks with a 10-inch clutch disc and nine-bolt pattern. Both used 139-tooth ring gears for the starter. After 1953, Chevrolet changed to 12-volt starters, and the number of teeth on the ring gear was changed, but there are still just a few different flywheels used (excluding Hydra-Matic and Powerglide automatics). Some of these flywheels were used on models from the mid-Fifties up into the Eighties. We have included some of the original casting numbers for easy reference. Flywheel #3704831 1954-'55 cars and trucks with 10-inch clutch Flywheel #373919 1958-'65 trucks with 13-inch clutch Flywheel #3739423 1956-'65 cars and trucks with 10 or 10 1/2-inch clutch and 11 5/8-inch bolt pattern Flywheel #3705409 1955-'62 cars and trucks with 10 1/2-inch clutch and 168-tooth ring gear Flywheels #3789730 and #3705410 1955-'62 cars and trucks with 11-inch clutch and 168-tooth ring gear Flywheels #3758595, 3714463 and 3789733 1955-'71 cars and 1955-'85 Chevy and GMC trucks with 11-inch clutch and 12 5/8-inch bolt pattern and a two-piece rear main seal.

Browsing Rock Auto in the (gasp) Chevy area for '59 and see a lot of 10.4" clutch options for the 235 I6...most are under a hundy for the clutch kit. Here is a Sach's clutch kit at 10.5"...$107
I put a Sachs clutch kit in my 65 Canso when I did the 327 4 speed conversion. Fit fine, worked great but of course I sold the car 125 miles after doing all that work.
When I was pricing out a clutch from the same supplier for something else about a year later they didn't do Sachs any more. When I asked why, they said too many issues with that brand. I haven't heard back from the CP member who bought my car since a few months after he got it.
