canjar set trigger for rem 700

where can i find a detailed schematic and parts list for a canjar set trigger? mine has 97 stamped on sideplate.
should there be a tension spring under shoe? removed shoe via pin and may have lost if one was present.
if so, who can i contact about a replacement?
thanks, any help/info will be appreciated.
