M38A1 CDN3 gas can/spare spacers

[chris vickery]

I was wondering if there are spacers required to mount the spare fuel can holder on the rear of my A1?
It appears that if mounted flush, the strap and can may interfere with the top edge of the back panel as well as footman loops. It looks like something around a 3/4" spacer is required????

Also, for the spare wheel carrier, there are 6 mounting bolts, 4 that go into the lower part into the body thru the re-enforcement gussets. The other two go thru the top at the top re-enforcement channel. At the top, the spare carrier also appears to require spacers????
