Custom gas engine standoffs?

Can anyone tell me where I can get custom-made aluminum standoffs: I have a RCGF45 rear carb engine and for the carb to clear the firewall I need 3" 3/4 inch (95.0mm) standoffs. The various RC outlets do not seem to supply them that long. Because of the vibration and toque forces I believe (rightly or wrongly) itís prudent to use single length standoffs rather making up the required length with two standoffs stacked on top of each other. Hence my question about custom made standoff suppliers.

My second question: As I have not seen standoff that long how long becomes too long?

I realise that the conventional solution is to build an engine-mounting box onto the existing firewall but if I can get away with long aluminum standoffs thatís the route I would like to go.

ought to have what you want.

You might also try using aluminum or brass spacers (threaded or unthreaded)
Now then

One old method is to use long bolts and some extra nuts to thread onto the bolts to set the length and use more nuts to tighten it all down with. If there is too much excess bolt length, you simply cut the extra off.

Or 1" oak dowels. I've done it for 40cc and G62. I use 10-24 or 10-32 all-thread. Havent seen a difference between wood and aluminum.

I realize that this is an old thread but I make custom aluminum standoffs.
