In order to understand what conversion mounts you need for your swap, you need to first understand your vehicle and the differences throughout the years. The motor mount and motor mount bracket in the following photo goes by a lot of names. A and B make up the Clamshell Style engine mount. GM refers to A as engine mount and B as a bracket. Nowadays, A is most commonly referred to as engine mount while B is most commonly reffered to as the Clam Shell. Engine mount is a loose term however and in order to not confuse the style of motor mount you have with the Early Style, you can refer to them as the Clamshell Mount. A can also be referred to as: rubber isolator, rubber mount, SBC/V8 engine/motor mount, "mounting, engine". B can also be referred to as: buckets, elephant ears, cups, motor/engine mount bracket, "bracket, engine mount", "bracket, engine mt". The Clam Shell Style started to phase out the Early Style Short and Wide/Tall and Narrow's in 1972.
OER makes reproduction Clams Shells but you have to understand that they are not a one size fits all. 2WD and 4WD 1973-1987 C10 will not interchange for instance.
A- Clamshell Mount; B- Clamshell
The clamshell itself (B) is no longer available from the dealership but the clamshell mount is still available at local parts stores. Clamshells are passenger/driver oriented as well. It is good practice to label them if you are removing them to install newer clamshell mounts to avoid any confusion later. You do not need to worry about acquiring the correct clamshell when using our EZ Mount conversion mounts.

Poly Insert Install Instructions
If your vehicle came with a V6, remove the mounts and install V8 Clamshell Mounts. Even though it is a four bolt Clamshell mout, only three holes will be utilized while the last one hangs over the engine crossmember.
Red marks the V6 motor mount holes while Green are the V8 mounting holes
V8 clamshell mounts in factory position
Some find it easier to raise the car and drop the entire K-member (AKA engine crossmember) to install the engine and then lower the car down to the K-member than it is to lower the enginer into the engine bay.
Conversion Motor Mounts
Dirty Dingo EZ Mounts are designed to bolt to the engine and the CNC cold rolled steel tabs will wrap around your stock clamshells. No clamshell that is NLA or modfications required! No more hassle acquiring the correct clamshells! These mounts will allow you to move the engine from the original bell housing position up to 2 1/2 inches forward, and up to 1/2 inch rearward. Low mount AC will fit but you will need to mount the engine forward from the original bellhousing position.

Power Steering
All the way up to 1979, the factory gearbox takes an inverted flare fitting. Unless some Previous Owner decided to use what they had on the shelf AND it was from before 1980 to get the vehicle on the road, then you have a Metric O-Ring gear box. Use the following information to figure out what fittings you need for your power steering lines.

M18x1.5 O-Ring |
If your O-ring is old and hard, use the following part number for replacements: GM 26001594 (Amazon)
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.
