In order to understand what conversion mounts you need for your swap, you need to first understand SBC GEN 1 motor mounts. 1967-69 Camaro’s that came from the factory with a SBC typically used Short and Wides while Camaro’s with a BBC used Tall and Narrow. You may come across an instance where a previous owner has installed Frame Perches from a different vehicle so it is important to understand both types.
This usually sparks the question, "Which one is better?". If sticking to rubber, the Tall and Narrow has more rubber to further dampen any vibrations. If going poly, its the same either way. If you spent the time and money to swap from Short and Wide to Tall and Narrow, you wouldn't really notice that big of a difference. If you look at the following example comparison photo, you can see the end result in height is about the same. Meaning it's not worth the money to convert what you currently have to the other style for something such as oil pan clearance. Use what you got and stop stressing over which one is best. The bolt pattern to the block side of the Early Style is the exact same and doesn't make a difference when choosing your conversion mount.

OEM rubber motor mounts last much longer than aftermarkert rubber. Poly mounts essentially last a lifetime and don't need to be replaced.

Power Steering
All the way up to 1979, the factory gearbox takes an inverted flare fitting. It is quite common to find a newer gearbox isntalled with a metric o-ring fitting instead. Use the following information to figure out what fittings you need for your power steering lines.

After 1980 Gearbox (Metric O-Ring) |
M16x1.5 O-Ring |
M18x1.5 O-Ring |
If your O-ring is old and hard, use the following part number for replacements: GM 26001594
DO NOT use any O-ring you find at the parts store. The Metric O-Ring fitting requires an O-Ring made of Viton so the power steering fluid doesn't destroy them.
O-Ring Technical Info: 903 (7.65mm ID x 1.63mm C/S or .301 ID x .064 C/S) Viton
If your vehicle has the Metric O-Ring fittings, then your power steering lines will bolt straight up to any power steering pump offered in an LS application. Make sure there isn't an O-ring already in the power steering pump from the old line!
If your vehicle has the SAE fittings AND the 3/8" lines line up to the back of your LS power steering pump, all you need is THIS ADAPTER to be threaded into the high pressure port on the pump. The power steering pump side is M16x1.5 with a Viton O-Ring while the power steering line will fit a 5/8"-18 Inverted Flare.
