    Front bearing - 7 x 19 x 6mm
    Rear bearing - 13 x 24 x 6mm or 14 x 25 x 6mm

    It would help to know what engine model/part number you have or the diameter of the crankshaft if possible (13mm or 14mm, where the inner bearing rides). The front bearing part number you gave is in the Reedy #802 121VS engine manual along with rear bearing # 23526 and specs indicate that engine has a 14mm crankshaft. That same bearing part number also appears to fit the Monster GT engine, I believe it has the 13mm crankshaft. The front bearings are the same for a few different engines regardless of crankshaft diameter.

    From what I can find digging through manuals, Boca and AE's web sites, your front bearing (#23525) is 7 x 19 x 6mm and is the same for both engines, but your rear bearing could be 13 x 24 x 6mm or 14 x 25 x 6mm depending on the diameter of the crankshaft.

    According to Boca, the Monster GT engine (part #23500) has a rear bearing that's 13 x 24 x 6mm. There seems to be some parts overlap between AE 21/Monster GT engine, the Reedy 121VS and Reedy 21VR.
