Solid trans mounts

[super vw]

Is having solid trans mounts a real bugger? as far as the extra noise and vibes?

I am thinking about geting a solid rear (rear is rear) mount then making my own front solid mount as i can seam to find any for the 1303 trans with the bellhousing style of rubber mount (metal bell shaped deal with rubber inside)
When i had the engine in the car before i remember it shakeing a lot upon startup and when applying throttle. I want to eleimintate this, im not to worried about a mild increase in noise but if its somthing thats to overpowering than i might have to think about this some more.

Im on a very tight budget so i cant aford to spend a lot on a Gene berg mount, when i could make my own.

Thanks,
Jonathan
