Did you have to cut down your 705 GTP frontrammer, like Kevin said. I have the Impact one and it has no provision to mount the body pegs on it 
I'm going to order the 705 Rammer 808121.
Yes, you need to trim the sides of the bumper to make it fit in the Lola shell.
The Impact one does not provide you with the body post mount but you could use your old broken or existing 705 upper bumper plate to use it as the front body post. See an old pic below that I had in my PC (not Mac
)

Anything else I need for the operation?
To convert the 705 to use GTP body, you need 3 things... The GTP set 808150, the Impact rear shock tower 808139 and the GTP / CanAm front bumper 808121 or Impact's more durable Lola bumper 808120.
