Opel CIH oil pan dipstick alternative option using Ford 7.3 V8 pan adaptor

Not wanting to have to drill the block to locate the dipstick hole where it should be for the manta in the block, i did a bit of searching and found the the US Ford 73L V8 Diesel has an oil pan dipstick!! So after a bit of measuring and checking i reckoned that this would be just what i needed. So i ordered one on ebay and when it arrived measured it and bought a metal hole punch to cut a nice clean hole and as i has a spare oil pan i thought i would give it a go. After cutting the hole and doing a test fit it looks good. I just need to get a dipstick that fits and then when the engine is fitted and fully filled with oil i can mark up the dipstick for the full mark.
