bluebird to avenir swap
well just recently cylinder four swallowed a butterfly screw and it beat the hell out of the piston so i half assed repaired it i just replaced it with a spared det rod and piston bearings looked untouched so i just reused it well i jus spun cylinder three rod bearing i mean it basically welded it self to the crank had to chizel it off so in other word the crank is scored badly so i was just going to order a new avenir det are there any major fittament or wiring differences between the two ? or with it be plug and play
