Anyone Running an LSA in a 63-72?

[JDon99]

Looking for anyone who has put an LSA in a 63-72. Specifically trying to find out if the stock accessory drive fits in the frame. Thanks fellas!

Installed an LSA in my 72 K10. Not running yet but you can see pics in my build thread. I never considered using the stock accessory drive because there are no provisions for a power steering pump. The low mount A/C would be close if it even fits.

Are the frame widths the same between the 2wd and 4wd? My LSA was out of a ZL1 so it didn't have the p/s pump but the CTS-V had hydraulic p/s. I won't be running AC in the truck.

I think so. For sure the same at core support. Think the 4wd frame raises a bit more than 2wd over the front axle area.

I don't have an LSA in mine, but the L83 I have does have a low mount A/C and it fits within the frame rails easily. I am also running a p/s pump on the lower drivers side using the GM Type II pump and there is plenty of room. I am going to run a remote reservoir though.

Who's mounts are you using?

I used ITC Billet. They have 4-5 adjustment front to back. I had to mount the engine 1.75" forward of where it originally mounted and trimmed the mount so the A/C compressor would fit. Everything came out nice.
