Dave, I think the Monte Carlo SS and Hurst/Olds & 442 used the same box. There's a few MCSS in local yard. I'll check Monday.
Let you know for sure if available. His prices are very reasonable, especially for me, as I've helped him a lot and sent plenty of business.
Rebuilt Cardone Monte SS steering boxes are avail from Advance Auto for about $122 using a 25% off discount code.... https://shop.advanceautoparts.com/p...ear-27-6550/3791467-P?searchTerm=steering box
I have a "fresh" one at my shop. I'll get it out and let you know the particulars on it. Thanks, Bob.
The one that I have is by Lee Power Steering Components. All fresh, never installed. If interested, email me for pics, etc.: drolds1@bellsouth.net. Thanks, Bob.
'92 -'96 Jeep Grand Cherokee uses the same box. Junk yard price $25 -$50. The one I put in my Skylark was $15 on Ebay a few years ago, and that included pump & hoses. Just bought a couple more for $25 each.
