Hi Terry, here's a few options I've used in my Sig LT-25 to mount about 4 different sized motors, all using the original firewall blind nut positions for the glow mount. The reason I went with channel instead of tubular spacers was a) those nylon tubes are not available in hardware stores here and b) consistent thickness without having to rely on precision cutting.
The image I don't have is the current setup - just a suitable block of 3/4" thick pine thru-drilled for the mounting plate plus a big hole for the motor leads and ventilation. Crude but effective.

Thius was for a gearbox thru the 'firewall', but could have an outrunner on the front.
This plat replaces trhe X-mount and is drilled for the original blind nut spacings
Some different thickness spacers from box and U-channel section aluminium.
OS 5020-490 in the Kadet using U-channel spacers - ridiculous overpower done for an OS power only fly-in
