Hey I usually stay on the cruiser side of the site but thought you guys may be able to help. I am doing a disk brake conversion on my 40 using mini truck parts. First question is: Are the asco hubs stronger or weaker than the aisin hubs? Second: Are the solid axle hubs and the IFS hubs interchangeable? Third: while I was disassembling my asco hubs the engagement gear came off of the toothed washer. The toothed washer has a spring wrapped around it and looks like it has to stay attached to help pull the gear back out of the hub to disengage the hub. I can't get this to stay on now how does this work? Fourth: I am also missing the large spring from one of the hubs can you get replacements? Thanks for you help in advance. Tom
